One moment, Marco is still trying to leverage himself over Galliard to get at Reiner - the next, all three of them are tumbling to the ground as Reiner reels back from getting hit with the rock.

Marco's elbows hit the ground, and he has the presence of mind to curl his arms up so his head doesn't get hurt. But in the next moment, he's trying to squirm out of Galliard's hold, even going so far as to hit his shoulder with a (thankfully rock-free) hand.

"Let me go!"

His rage is starting to burn out, not that it's very obvious. His gaze hasn't left Reiner, even as he tries to knee Galliard in the chest.

"Why? Why did you do it?!"
