He doesn't plan to grab the box until just before he makes his move. Patch can see that. Or rather, she doesn't see the decision to grab it telegraphed in his moves. So does he really want it, or is he just mad at her? Either way, this box showed up in her path, and it's hers to deliver, and she's pretty sure just handing it off to some random person doesn't count. Besides, freaked out and sleep deprived and sick though she may be, this package used to be somebody, and even if she can't stomach the idea of carrying it around, she still feels obligated to figure out just how he ended up here.

So, when Qubit's hands make contact, surprisingly fast for someone who didn't even see the lid coming at him, Patch digs her fingers into the ridges of the moulded plastic handles and refuses to give it up. "Let go, or I'm going to kick you," she warns, with cold determination to do her really distasteful duty with this thing.
