If he had a shilling for every time he found himself dangling off the edge of something, Jamie thinks, he wouldn't necessarily be rich, but he'd probably have a nice tidy sum.

He's grateful that Kaylee's there to steady him, and he's able to improve his grip on the hatch - and with a little scrambling, find a foothold. It hurts - whatever he twisted is protesting vigorously at the strain.

So (perhaps luckily for Kaylee) he's actually very quick to pull himself up, grunting with the effort.

He gets himself through the hatch and inside the tank, and just lies there for a moment to take a few deep breaths - then belatedly realizes that Kaylee's gasp was probably not just from worry. He looks up to the hatch to see if he can spot her.

"Kaylee? Lass, are ye alright?"
