Danny Pink
So is he really dead? I would quote Rory as a precedent here, he did die on several occasions but kept bouncing back. Pink ended up in a place where he was able to make a choice to send back the boy instead of him, which implies that wherever it is may well appear in a later episode for him to be rescued. The clue is in the meeting with his offspring. Chances are he'll reappear in Clara's last appearance with the Doctor, so she can settle down with him.
