There'd been too much chaos happening on the battlefield that Garreg Mach had become. Somewhere along the way, he'd heard from the others that they'd lost sight of the Professor, someone claiming that either a monster crushed him or that he fell to his death. Either way, it sends a feeling to the pit of Ashe's stomach, and too quickly the fight loses control as soon as they lack their teacher.
Ingrid swoops down on her pegasus briefly to tell him: "Lady Rhea is missing, and Dimitri's told us to evacuate! Hurry and escape!"
All Ashe could do is nod, then take off to find his way through the fight, grimacing as he tries to not look at the corpses of knights and soldiers. Maybe there are still other students out there, dying to Edelgard's ambition. It's hard to say. In a corner, he spots Linhardt sighing, healing Caspar's leg before they prepare to take off, and understandably so. They chose their friends over the Empire; he isn't even sure where they have to go now, but they have each other at least. Petra paves the way for them, and Ashe thinks they'll manage.
He stops to crouch behind some rubble, taking aim and firing off an arrow at a stray soldier daring to creep on them. It's one more down, one less enemy for them to worry about trailing them.
Continuing on, he makes it back to Garreg Mach, uncovering his satchel. He'd packed it, just in case, because nothing is permanent, a fact he regrettably understands. It has some of his books, but more importantly he has food and water. He starts to step out, watching Leonie struggle with her desire to avenge Jeralt and the Professor as she is reasoned with by Claude, who grins and bears it because it's what he does. On the horizon, he watches Dedue faithfully follow Dimitri as they help others escape, praying he sees them again soon.
He almost leaves entirely, if he didn't stop to notice a familiar face, collapsed and injured.
"Felix?"
