Guppy's gut feeling is to say 'I don't know how much more of this I can take'.

But he doesn't, because he doesn't have a choice; it's take it or die.

Everything seems to be going wrong, and he's struggling to have faith that they're going to make it through alive.

As the ship gives a judder, it occurs to him that he hasn't taken his motion sickness medication. However suddenly that doesn't seem very important any more.

"Let's get you cleaned up." he manages to say to Will. "Put plenty of pressure on the wounds, get some kolto on the pads to speed it up."
