OK so from Darcy's perspective this isn't actually a terrible plan. All the scans and all the over-the-top analyzation hasn't exactly gotten them anywhere, right? Taking hourly logs of her biosigns and keeping track of every breath she takes-- that might actually be the crazy thing to do. So as much as Jane wants to roll her eyes and walk out, the quiet desperation wins. Craft herpes it is.

Which means Jane does roll her eyes but instead of walking away, she waves Darcy on to continue, silently. This is so not moping. It's ... determination to prove Darcy wrong. Yeah.
