Antonin Dolohov (2)
Antonin only had an Incendio burn on his right arm and some bruises from falling hard against the ground, so he was fixed quickly and then dismissed; he would have waited until Tom (or Lord Voldemort now, apparently) was stabilised so that he could stay by his side (for half an hour), and then would have gone looking for Cressida, Ernestine, and the other boys.
