And yes, I do like the friendly hello idea. Takuto would TOTALLY wave and smile and say hello when he sees people he knows.

Takuto can sometimes turn a disgruntled friend into a good friend, and I think given the circumstances, he knows to look past the disgruntlement and see it for what it really is: HE CARES (about Cloud).
