After a second to recall what he'd heard, Loki laughed. Sakaar and this Grandmaster, yes. It was very slightly annoying to lack his own context on something that both Thor and Valkyrie knew, but not unduly. On the whole, a better reaction seemed to be 'continue to look forward to that experience'.

It helped somewhat that the more he heard, the more fun it sounded like he was going to have. "Not impressed, I take it? No matter. I doubt I'll be having company tonight."
