Their feud first began on the very first day of TDI, when Heather clearly stated that she was not jumping off of the cliff. Leshawna, not wanting to lose, forced her off, and eventually threw her off the cliff. Later, Heather faked apologizing, thus signaling that this wasn't going to be the end of the feud between Leshawna and Heather. In almost every episode the two went at each other from forming alliances against the other, to pulling pranks, and even violence.
Leshawna has not totally forgiven Heather, mostly because the former queen bee was responsible for voting her off of TDC. Thus, the two are still at odds, but because Heather is trying to be nicer for Ezekiel's sake, she is not openly aggressive towards Leshawna.
- This is one of the most heated feuds in Total Drama history, the others being Gwen and Heather, Courtney and Harold, Yoshi and Zachary, Colin and Hannah, and Anita and Eva.
- This feud is even hinted in the Total Drama Island opening sequence, were the two are on a boat slapping each other.
- So far, during this conflict, Heather has stayed on the island longer than Leshawna, in both TDI and TDC. This has only fueled Leshawna's outrage thus far.
- Leshawna - "If you had told me during Total Drama Island that Heather was human, I would have doubted you. But you know, she sure is changing, and I don't mind that one bit. If Harold can accept her, maybe I can too!"
