The sound startles him but truthfully Jim doesn't have the strength to go throwing himself off of beds so swiftly even if he'd be liable to in most other situation. He won't even make it to getting a foot planted on the floor before Felix is there assuaging the knee-jerk fear that somehow Jim was alone back here. In the snippets of half-remembered consciousness he was sure he'd heard Felix's voice.

"Wh--" Felix is gone before he can stammer out a question, before Jim can organize his jumbling thoughts into any kind of facsimile of order. Felix is here and they're back on the ship. It's as far as he'd gotten. His hands shake with the glass enough to spill a bit over his shirt but the water is clean. The thought makes him shake again. He's going to finish it before he even thinks about setting the glass aside.

"How...?" The captain's voice is tight with emotions barely held in check. Anguish and tears he's kept from spilling all this time.
