His first thought is, huh, no mask. But, hey, Sanguine doesn't wear one either -- no point, unless he wants to go full bodysuit with gloves and everything. The silver eyes miiight be contacts? Armor, shield, sword, cloak, all very medieval chic. Looks heavy, but it clearly doesn't bother her. Yep, Dragon was right as usual: this person has been caping, or doing whatever her world has instead of caping, for quite a while. Her apparent age doesn't really register; he meets a lot of super-powerful teenagers in his line of work.
Also, geez, why are all high-end capes so hot. Except Eidolon of course. He's not going to do anything about it but like, a man observes what he observes.
At ground level it's clear that he's a little shorter than Samora.
"Well, mostly this is 'sposed to be me helping you. Dragon said you're from some other Earth, and you didn't come here on purpose?" He shakes his head, laughing a little. "Of all the times and places...you've got some kinda luck, lady. But I'll fill you in, no problem."
"But yeah, we gotta do the pathogen screen. The way my power works is, I can do all kinds of stuff with blood." He just barely restrains himself from doing his usual Bela Lugosi impression; she probably won't get it. "So if you give me a drop of yours, I'll compare it to a sample I got from a guy downstairs," he pulls a little potion vial out of his pants pocket, "and we'll see what we see. Mine wouldn't work, it's special. It'll take me a little bit and be really boring, so if you'd ask me some questions in the meantime I'd appreciate it." Dragon also wanted him to get a survey of her powers, but Sanguine figures they can work up to that.
He doesn't move toward her. He's got a syringe in his other pocket but between the sword and her general attitude she seems like she can draw her own blood sample.
