"Communication? How? By yelling at it?" Draco lifted a blond brow, doubting the fact that this device could actually be used to speak with someone else. But, this was Theo, after all, and who else could he trust but an old friend like this? Theo wouldn't lead him astray, not like Potter or anyone else Theo had mentioned.

"I won't have you waiting on me like a bloody house elf. If anything, that's what Potter can be good for. But I won't say no to a proper cup of tea right now. I haven't eaten yet, Merlin no.

He crossed his arms, trying to maintain a sincere expression, but also trying hard not to lose it over all of this new information. At least not out here in public where anyone could spot them.
