Sol, for his part, doesn't really know why they are looking at Marcantonio at all, unless there is something brewing in Theo's mind to tie it all back to the murderer - which is what Sol has been hoping. If he's honest, Sol doesn't have a natural inclination toward mysteries. He knows that there are people who enjoy a good intrigue, like to pick at the bits and pieces and try to formulate, to project a whole. Not Sol. He wants to touch, to smell, to feel, to experience the whole of a thing, not try to make it up from bits. He likes solid things that he can explore all the angles of, but something so vague as all of this does nothing except frustrate him. And so he doesn't have theories on the Marcantonio files, he's just crossing his fingers that Theo, that the man who does deal in mysteries, has some kind of reason for spending his time chasing down this line - some kind of reason that ties back into the case.
When Theo jokes about the vents, Sol's brows wing up. "I considered it," he admits, and at least for his part, he isn't joking. "The vents in that part of the building are large enough for a moderate-sized man to move through," he adds, and though he doesn't say exactly how he came to be in possession of that fact - well, you never know until you've tried, do you? He's just glad he isn't claustrophobic. "Picking locks wouldn't explain the barricaded door with Catherine and Joselyn," he adds, quirking his brows.
And then he's distracted by the change of topic, and his brows go ever higher. "Does she know it's a date, or is that just what you're calling it?" Sol asks, containing a smirk.
