The kindness of strangers, Arabella being amazingly competent, a small garden, and knowing which wild berries and herbs were good enough to eat. That's how Strange survived but really, it was mostly due to the first two options.

"Perfectly fine," Strange lies, despite the fact that it is amazingly apparent that his dinner's coming along terribly. At least he's decided on what the next step of how to cook a nug is: gut it and take out the organs. Or at least, that's the next step on how he's cooking the nug. Drawing a slit across the animal's belly, Strange gingerly tries to cut out the heart, lungs, et cetera...until the knife slips in the wrong direction and the blood and bile and internal fluids just squirt in Strange's face. Unfortunately? He's about to sass something at Solas before the knife slips so a little bit of the blood/bile/whatever gets in his mouth.

Nature is awful and he hates it.

"Funnily enough, I'm not hungry anymore."
