Honestly, Mobius knew that things were going too well - why have a ten-day feast and then not encounter an assassination? Especially when there was so much tension to begin with; it just hung in the air.
He didn't have his baton on him, unfortunately, but he did have a TemPad. And an iron fire poker he'd snatched from the din and cacophony of the feast - which he was prepared to use as a weapon even though, honestly, he wasn't much of a match for energy-wielding elves with a crap ton of bones to pick. The TemPad was what he focused on though, plugging in a few coordinates and opening a Timedoor out (just beyond the dining hall, away from the calamity) - the familiar whoosh of that door shimmering into existence was actually a comfort; he'd ensure others got through, but he was going to stick with Sharon.
"So this is fun," he started, clutching the fire poker in a white-knuckled grip. "I was hoping that some mortal peril would add a dash of spice to the endless eating and drinking." God. It was like either being in an episode of Game of Thrones or a Shakespeare play - was someone going to emerge from behind the drapes next? "I can open another Timedoor to get us out, but - I wasn't sure if you wanted to help or not. I'll follow your lead."
Sharon was Going Through a lot, in terms of shifting priorities and her changes with her role in Madripoor - he was here to be supportive, if she wanted to dip her toes back into HEROICS. Or if she didn't want to.
