NPC charming my pet

[Bristlebaner]

I'm looking for some guidance on the mechanics of how this works.

I'm in ToFS on my enchanter. The 2nd level is a bunch of enchanter mobs. They occasionally charm my animation. It starts attacking me. I can recharm it, and the pet window reverts to it's prior state of only having the "Go Away" command available, despite it not being a permanent pet any longer.

If I camp out, it does appear to poof the pet, despite it no longer being my pet.

Shouldn't the pet revert back to being my pet after the NPC charm wears off it, or does it forever stay a "wild" npc from that point forward?
