My mention of introductions is because first introductions matter. For instance in the early dev of password Roswell was an absolute C*nt, berated Dave, was a huge asshole to everyone. Roswell was re written 2 or 3 times since then but i still lothe him entirely becuase of thoes first impressions.
Liam's introductions is quite a wrecking ball to his likeability.
The coffee cup gives affection and also can give easter eggs.
Entering a characters name like Tyson will give +1 affection to that character.
Eddit: Also gives new text of Dave and Roswells reactions.
Entering Dave gives +1 affection to all characters.
There's some easter eggs with patreon names, the only one i remember is Timber, or is it Timbre? I think it's Timber, this changes the bus driver who drives you to the mansion.
