Some for Logan (Why did I make Logan's headcanons so depressing?!):

-He actually has feelings but he doesn't like showing them because it makes him feel weak

-He secretly loves Patton's puns but pretends to hate them so Patton would fanboy over him

-Logan LOVES space. Like he really loves it! He has a telescope in his room and he has glow in the dark star stickers all over his walls

-He is touch-starved so when Patton hugged him for the first time, he didn't know how to react and just bursted into tears in front of him

-Patton is the only one who Logan will cry in front of. Logan trusts Patton enough to let him help him with his feelings
