This is more of a question than topic, but I've noticed that with each new character I play in Changeling, when I first get to choose a topic to study the options keep getting less and less?  I  thought it was just taking away the ones I've already picked for  some reason, but it took away the 'wizards and witches' option which I hadn't played and was going to, so I'm a little confused.  

Any light shed on this would be very appreciated, and sorry if this is in the wrong place. 

The menu there is based on your previous choices. If an option doesn't appear, it's because you skipped out on a chance to interact more positively with that particular character.

For instance, if "witches and wizards" disappeared, it was because you did not dive in and rescue Corvin's book when you went through the common route! 

You can unlock a total of 5 love interests at a time (you can't unlock Marc and William simultaneously) so if you want to have all the options open I'd recommend:

- picking backyard or front yard will unlock either Danny or Elliot.

-So if you want the other one unlocked at the library scene, when you're in Literature and have the chance to acknowledge one of them, wave to the one you did not choose in the boxes vs bins choice. (In other words if you chose backyard and met Danny first, wave at Elliot in class. This will unlock both their options).

-When given the choice to sit beside Marc or William, I'd create a save here so it's easy to go back and swap them out.

-Make sure to dive in and save Corvin's book.

-Accept Ewans offer for a red home.

Then I'd just make a save at the library choice to be able to easily go switch between routes. 

Hope that helps!
