Akechi turns back, and In his own habbit raises a hand to refurnish the high five before they both stop.

“…I’m not going to get time traveled or something if we high five, right?” Is what he says instead. Look the tape didn’t exactly give him context here.

For better or for worse he’s a little more relaxed about these things.
