That's not something Tau misses, but he can understand it plainly enough. Those brought through the Servant's Gate weren't dragged into this world for a family vacation. His own expression is politely neutral at that.

"I'm sure we all will." He nods, raising a hand to wave as he figures the big guy is going to head on his way. The thanks is unexpected, maybe, given Tau's expression. He blinks, but then offers Raph a gentler smile at that, nodding.

"Stay out of trouble. See you around, Raph."
