Sasuke is going to be mopey mostly. He was just out of jail when he arrived in Woodhurst, so being in jail again after experiencing such amazing and dangerous freedom? Not fun. He's sporting a nice and bright HH on his forehead, that's mostly covered by his handy dandy bangs, so unless he shows you, you probably won't see them clearly.

He's going to stay away from the fighting in the raid, not really caring for anyone but Naruto himself; he spent way too long in dark, solitary confinement to go back to that voluntarily. No, thank you.

He's rooming with Sai during his stay in cool space jail.

So yeah, if anyone wants a brooding teenager to talk to while in jail, here's your boy!
