There's a figure stealing along in the shadow of the wall, trying to get her bearings. Rikki and the giant robot dude notwithstanding, Ellie has Things to Do. These things don't include being roped in to whatever mess these people are floundering their way through. Her life is complicated enough.

She can see things moving in distance, blurry shapes that seem aimless from where she's standing, which tells her going straight north is probably stupid. She'll lose time getting to that Hollows place, but it's better than getting ripped to pieces. Immunity only does so much.

West, then north. Maybe she can find cover before the change.
