Marta's eyes go a little wide, but otherwise, she seems to take the news more or less in stride. It makes sense (no it doesn't) and there's no real point in panicking right now (isn't there?). She swallows, and startles a little when the crowd cheers about something on the screens she can't see, and then swallows again.

"Is it possible to get something to eat?"

When in doubt - attack the problems you can do something about.
