Fred might have bounced a little. She did like random parts boxes. She especially liked them in Annie's shop because sometimes she found parts that went elsewhere, which meant there was more story or something in Annie's shop felt more complete. She might not be able to hear the machines, but that didn't mean Fred couldn't feel pride.
"I think this goes to a pump I saw earlier." She really wasn't listening to the powerful blondes. She knew what was on the phone, and she knew that Annie could do something about it. Or she believed Annie could. Fred was a scientist who'd lived in a demonic world; she had faith enough to split atoms.
Setting the small part aside, she started digging through the rest of random bits. Absently she started organizing the pieces parts, and it was according to a method only she might understand. At least until someone asked.
