Anyone know what episode this cel is from?

[Adam Riches]

Hey gang,
Hoping I can put our collective toon knowledge to use...

I picked up a bunch of animation cels today, most of which are easy enough to identify, but I'm having a hard time pinpointing this April cel.

I imagine the scene must be set in shadow or something because her jumpsuit is darker than all the other April cels I have, and her watch band is not white (though that could just be animation error).

So far I've watched though the first 8 episodes and no matches, but it'd be cool to figure out without having to rewatch the whole series (though I don't mind doing that if I have to!)

Any help is much appreciated!
