Zelnick made a non-committal noise-- aside from the odd greenish tinge and general look that ZEX had no idea how to take care of it, there wasn't anything actually wrong with it-- and ignored the lecherous smile to go to the dispensers along the wall. Lessee, this one was shampoo, right?

Pumping a generous amount of the stuff into his palm (probably more than he needed, but ZEX's hair was kind of wanting for it), he turned back to ZEX, standing behind him (blocking most of the shower's spray) and beginning to work the shampoo into his hair.

He conveniently ignored that this was probably really, really intimate looking to anyone else. Just washing a friend's hair, nothing to see here, at least he isn't clinging now...
