Loki can feel the silent vibration of the cellular even when it's squirreled away into a handy pocket dimension - his armor hardly has an appropriate pocket for this sort of thing - and dismisses it. Given whom the captain was conversing with, he can guess the caller. Family. What can one do?

Levering himself out of the seat, he cants his head and tuts. "Must you even ask?" It's said with the air of someone who knows he's speaking to someone who obviously knows better. His staff materializes from another pocket dimension and he grips the cool metal with his hand, standing with one hip jutting out and a lazy confidence on his face. "One would assume that by now, at the very least, you lot would have learned not to wander out alone. It almost becomes too easy like this."

Not that he's complaining, mind.
