[Sylvain props his chin on his hand, grinning briefly for that threat—promise?—but letting it slide. If he ends up where he hopes to, there's no way Felix or Dimitri would be willing to drop by his work to give him a hard time. Not that he doesn't have his own motivations for putting in a more than serious effort, but no way in hell—hah—is he admitting that.

His expression sobers again as Felix starts summing things up. That's kind of a lot to take in, and knowing Felix, he's barely skimming the surface of things.]

Wait, what's that about senses?

[And monsters, but he lets that pass with just a brief flicker of chill in his eyes. This place is already full of monsters, but that sounds like a distinction.]

So if you think the point wasn't killing him, what were they trying to do? Stir up trouble between the clans? How'd you hear about the tower stuff?

[He's trying to keep his questions to a moderate amount, but the more Felix says, the more he knows how much he doesn't know. And Felix might be brusque, impatient, hotheaded, and short-tempered, but he's always had a good head for practical tactics. Whatever he's observed already is a way better start than Sylvain is going to get just wandering around the city and listening to gossip.]
