I’m beginning to have doubts over whether this episode is a WW episode or whether this is a Tinkerbell episode. Normally the villain centrics don’t happen until towards the end of their villain arcs, this episode is happening in the middle of the mini-season
Also Tinkerbell is called Green by Blue. Perhaps this episode shows how Tink got to Neverland or maybe it’s what Tink did that made Blue say she was already on her second chance. Maybe it’s how Tink met PP and supposedly became one of the people he could trust.
