Strange simply rolls his eyes, giving Solas a frown. Yes, his knife play could use work. Yes, he could do better. But dammit, he's a mage, not a fighter! If he needs to take care of something, he'll use magic instead of knives!

"I'm a mage," Strange responds, with a roll of his eyes. "Forgive me if I need some more experience in something I rarely use in the first place."

And for all his complaining that he's not hungry...he still kind of is hungry. So out of a combination of stubbornness and hunger, Strange goes back to trying to gut the animal. They'll be here for a while.
