He's now eating the mouse again. Should I hope that he got it out of his mouth or whould he have just given up and swallowed it anyways?
As long as he hasn't swallowed too much he should be fine. Keep an eye out to make sure he is still pooping and the aspen hasn't blocked anything in his digestive tract.
