[Riku won't notice it - Terra tends to be sneaky sometimes, and it helps that Riku just isn't paying attention to what's going on around him.

All to Terra's advantage. He 'sneaks up' behind Riku, kind of leans over, and proceeds to use Riku's head as a make-shift armrest.] He started to sparkle like someone dumped glitter on his head the second I ruffled his hair.

[Yes, that is a teasing tone and smirk he's adopted. It's a little eery, Riku-ish that smirk and tone are. He then looks right at Sora and tilts his head slightly, the almost playful look still on his face.] Is this a recent development?
