How do you do the hyena route again?
Some spoilers below:
I'm assuming you mean reaching the dinner with Reth, as that seems to feature the most Reth-related content.
Starting a fresh game, choose whatever until you reach the question "Tell me, what else do you desire?". Do not choose 'Love'. This will boost your charisma by two points, and you need to have ten (the default value) when you meet Silas.
The next question will have two options that grant charisma. "A lover" and "Friends" both grant one charisma apiece. Those will leave you with eleven charisma, so do not pick them!
Choose whatever until you reach reach Silas. As stated earlier, lie to him when he asks if you are going to the academy. If it interests you to know, you get one charisma point for lying to Silas so you now should have eleven. If you had twelve at this time, he would give you a ride.
The time that you spend with Alderic doesn't seem to affect any interactions with Reth, so choose what you want during his phase of the game. Eventually you'll meet up with Silas again and get a ride to the academy, where you can choose whatever last name and major you want. Orion will drag both you and Reth to the academy tour, where you will have the option to ask about the room with the large black pots. Do choose to "Ask Reth". This is your only opportunity to get the needed favor from Reth.
Take any choice until you reach the showers. Do not peek at Reth! You won't even be able to ask him to join you at dinner if you do. If you successfully resist the urge to see naked hyena, and did get the two points of favor by asking him about the room, while drying off afterwards your character will automatically invite him to eat with you.
Unfortunately, right after the dinner is also the end of the current build, so there isn't much to Reth's route. Hopefully this will be expanded in the future.
By the way, if you initially choose to tell Silas the truth you can still get some favor from Reth by selecting "fight back" and choosing to ask him questions during the tour. However, you won't get the scene with the shower nor invite him to dinner. You will get the option to have him guide you to the admin office, but this will lose you favor with him.
There is, yeah. I'll outline the steps below:
When your character has the nightmare and has the option to talk to Silas, you can see him naked if you enter without knocking. However, you have to have him like you enough.
With Silas, you'll want lots of intelligence. This gives you more chances to get on his good side. When starting a new game, choose "I remember". This gives a point in both intelligence and wisdom.
The next choice doesn't matter. Strong is what I normally pick though.
At the next menu, ask all of the questions! These should be: "Grasp","Between place?" and "Who are you?". Asking all of these grants a point in intelligence.
At the next menu, choose "Knowledge" as what you desire. This gives you another point in both intelligence and wisdom.
At the next menu, you can choose any. "Friends" or "A lover" both grant one charisma, while the others grant nothing, so might as well pick one of them.
Name and customize your character. These don't grant any stats, so pick freely.
Wait or follow road until you meet Silas (Exploring the field is fine too). Do tell Silas the "Truth", this grants two points of favor with Silas.
Next, you should get to ask Silas some questions in the carriage. I don't think these matter outside of asking about "Magic", though I recommend clicking through them all anyway just in case. But definitely do ask about "Magic", and do accept the offer to learn magic from Silas ("Yes").
If you have enough intelligence points, the lesson will give you three points of favor with Silas. You'll know you had enough intelligence if your character starts glowing.
When you reach the toast, choose "To magic". This gives three points of favor.
When you reach the tent, choose "Cuddle with Silas". This gives two points of favor, and based on which position you want Silas in can also grant charisma.
Bath options aren't important in this situation, but lavender will grant more intelligence and wisdom and we seem to be maxing those anyway.
While washing the dishes, choose "Joke". Being "sincere" only grants three favor, while joking gives five.
After the dream, choose "Go tell Silas". Immediately after, choose "Go in". Silas should be naked upon your entry, and disappointed that you didn't knock
Thanks a lot! I did most of the stuff that seemed obvious for gaining his interest, like the first choices regarding intelligence, truth, learning magic... But I didn't know minor choices affect the stats. That must have made me miss it the first time. Can we see Orion naked too? I'm guessing if it happens, it will involve initial decisions that increase strength and stamina
We can indeed see Orion naked. Fortunately, he's an easier one.
For Orion, you only need two things: High charisma, and get lost before orientation.
You can actually just follow the Silas guide, with two exceptions. First, choose "Love" as what you desire instead of "Knowledge". This gives charisma. Second, when you are at the tent scene and select "Cuddle with Silas", choose to make Silas the "Little spoon". This grants more charisma than making him the big spoon.
By the way, in the Silas guide the route I gave gives more intelligence than is actually necessary, so with the first change you can still see Silas before getting Orion.
The next choice after you finish the altered Silas path should be Silas offering a tour at the academy. Neither choice here matters, though I recommend accepting.
If you didn't give Silas your last name in the carriage ride, you'll get to make one when you talk to the woman at the admin office. Once you finish with her, you'll get to try to navigate the halls on your own. Do so incorrectly by only choosing "Right" and you'll be lost in no time and successfully find Orion in a towel.
Orion will take you to his room so he can change. When he asks you to turn around, choose "Don't". This option only appears if you have high enough charisma. He'll ask again, to which you should choose "Don't". Orion will then lower his towel and his opinion of you, so maybe not the right choice if you want to be his best friend.
