I HAVE MORE CHAOS ENERGY TO ADD!
Also in this annual, Tim's best man at Dick's fake-wedding!
(True brotherly love: helping out when your pseudo-brother fake-marries a potential murderess. Look how serious Tim is taking this responsibility. I think his curled hand is guarding the wedding rings. Plus, imagine Dick and Tim shopping for those matching outfits.)
In more friendly violence, here's Tim visiting Dick's apartment in Blüdhaven (Nightwing 6):
Tim breaks in and hides in the dark, and Dick tackles and pins him. (It's how they say hello?)
Plus there's my all-time favorite, Gotham Knights 8, when Tim is trapped and Dick keeps shushing him:
(I think in the last panel Tim's doing a forearm block?)
More friendly violence in Legends of the Dark Knight 120:
PLUS there's that time in Robin 118 when they're worried someone might be watching them, so they fake a fight and it looks like this:
(before you cast doubt on their acting skills, though, consider this Actual Footage of Tim shouting at Bruce on a rooftop, and Dick doing the "I THROW UP MY HANDS AND STALK AWAY" pose)
they're dramatic morons and i love them. xD
