Robin has just enough time to think that a grin looks good on them, before a number is presented to him in the form of a question.

Vincent, misunderstanding, speaks up from his end of the couch, "Until you can get your shit together, or Robin solves his fuckin' mystery."

Robin heard it correctly, tilting his head while he tries to think. There are only two of them here, aren't there? Unless they meant someone downstairs, or... He tilts his head the other direction, coming to rest it on the back of the couch, looking down at Phalanx with that same, vibrant curiosity he'd shown a second ago.

It's four if Robin counts the others. Like the twins, the birds, the writing on the wall--"four" is another little coincidence that makes him think Phalanx really does have some greater understanding of the truth than most would believe. But whatever it is, fluke or not, Robin supposes the other two would be in agreement if they weren't potentially entirely figments of his own unsettled imagination.

"Yeah," Robin tells Phalanx, completely separate from what Vincent had said, "Everyone."

"...Huh?" Poor Vincent.
