There was no way Pollock blocked KP intentionaly. It was shown a zillion times from all kinds of angles and it was always the same. It happened spontaneously. As was his immediate concern for KP.
Kp's response to Pollock showing concern for his 'hurt' also showed that even KP did not think Pollock was to blame for it.
It was unfortunate for KP but completely withoyt blame was Pollock.
