Once Robin can see that Phalanx was clearly distressed, he stops his whining in favor of leaning closer, quickly reaching to run his fingers through their disheveled hair.

"I had no idea..." He admits, sounding a little guilty (which is rare), "Phalanx, what happened?"

But before Phalanx can even start to consider pulling some kind of an answer together, Vincent fills in the words for him: "He said something about there being... something, and then everything was gone. Like, uh, and end of the world thing. Except emptier, probably."

Vincent doesn't mean to rob Phalanx of the chance to talk... But if it was tough for them to explain the first time, he doesn't want to make them repeat the effort another time if they don't have to.
