Prometheus has the advantage of having lived with humans for most of their existence. Although he isn't ashamed to look something up if he is clueless about it. "You can text me, too. Or you can embrace the fact that you're out of date. No one hassles me about it." Of course, considering how he has a tendency to treat all humans as though he's their benevolent uncle, or a proud sports coach, the out-dated slang fits his persona and ends up being endearing rather than irritating.

Tony Stark would probably still give him a hard time, though. You can't please everyone!

The Titan wordlessly pats Thor's arm again. Not such a small thing, he'll do his best to find out her whereabouts. "No, I don't think we've talked about Sif. I've read about her, of course, but the myths are not the same as reality. They really don't let Asgardian women become warriors? What about the Valkyries?" There's also Thor's creepy sister, but he's not about to bring her up again.
