Provoke was considered a crowd control skill. Its effect could generate a huge amount of aggro, while causing the Taunted target to lose its free movement. It could only attack the character who had cast Provoke for the next 3 seconds. Unrivaled Super Hottie activated his Knight's Spirit, which caused his Provoke to be enhanced to a Glorious Provocation. It generated even more aggro and would increase the forced attacks towards the caster to 5 seconds.
There were many NPC's that were immune to Provoke, but Bone Dragon Aldton wasn't one of them. After getting Provoked by Unrivaled Super Hottie, its attention shifted towards him instead of towards the other players.
Using such a skill in the event of an accident was what a MT would usually do. Crispy Bean was very adept with such methods. The problem was that his Provoke was still on cooldown when it had happened!
