Heather and Sierra

This article is about the conflict between Heather and Sierra.

Overview
The conflict begins in the first episode of Total Drama World Tour, where Heather is pretending to like Sierra and wants to make an alliance with her. However, due to having watched the previous seasons, Sierra knew about Heather's tactics and knew that Heather was using her for an alliance. Throughout the rest of the season, Sierra pretends to be friends with Heather, until Heather's actions towards Cody in Sweden Sour cause Sierra to attack her.

In the confessional Heather says "I do NOT heart the new girl". At one point, Sierra sets off a trap that sends a row of arrows toward Heather's head, Heather is visibly angry, but she is able to control herself and pretends to forgive Sierra. Heather joins Sierra in a group hug with Cody, although she seemed reluctant to do it. Sierra seems to be unaware that Heather dislikes her, which appears to be quite odd, since Sierra supposedly knows everything about the contestants and should know of Heather's manipulative nature.
