1) He'll never admit it, but he gets slightly emotional every time you gently touch his scars because he's not used to that kind of softness, but he really loves it
2) If you have beauty marks or freckles on your face, back, arms, etc., he's the type to gently trace them and connect the dots like constellations
3) He always comes straight to you whenever he starts bleeding out of his staples because he knows that you'd never hurt him and patch him up with the utmost care
4) If Toga's having a bad day and he notices, he will flip a switch and become a big brother — he'll play with her hair, do whatever she wants, and just comfort her
5) When you cuddle, he lightly traces patterns onto your arms, back, etc.
6) There's definitely a lot of playful banter where he'll go "cmon, baby, why do you have to be so mean?"
7) If he catches you staring, it's definitely "take a picture, sweetheart, it will last longer" followed by a wink
8) He definitely struggles from night terrors every now and then, and that is the only time you are allowed to be the big spoon
9) He loves when you wear leather jackets and/or combat/platform boots
10) He doesn't say I love you often, but when he does, it's in the middle of the night when you're both half-asleep; but he means it every time
