Alejandro and Sierra

This article focuses on the interactions between Alejandro and Sierra.

Overview
Alejandro and Sierra were both newcomers to the competition during Total Drama World Tour. Unlike the other girls, Sierra outright despised Alejandro from the start and was one of the few females to never fall for his charms. Both were initially put on the same team before Sierra switched to Team Amazon in order to be with Cody. After the merge, the conflict intensified as Alejandro repeatedly attempted to break the bonds between her and Cody.

Sierra and Alejandro were initially placed on the same team. After the others are unable to think of a name for their team, Sierra came up with Team Chris Is Really Really Really Really Hot. While Chris likes the name, Alejandro and the others do not. Alejandro then curses in Spanish while using the confession, complaining that he is in a team with a bunch of incompetents.

Sierra is the only member of Team Chris Is Really Really Really Really Hot who isn't impressed with Alejandro's motivational speech. She also adds that any girls who like him are crazy.

Broadway, Baby!
For most of the episode, Alejandro tries to prevent Heather from forming an alliance with Sierra. While climbing the Statue of Liberty, Alejandro convinces her to help Chris revisit his glory days, because he thinks no one cares about him anymore, leading her to reveal lots of Chris's embarassing past which angers him. As Sierra was intially only useful to Heather because of Chris's affection to her, Alejandro therefore destroyed her usefulness to her.

Slap Slap Revolution
After seeing Alejandro slap Cody, Sierra becomes upset and kicks DJ off of his platform out of anger. The two are the last contestants left in the challenge for their team, and Sierra was able to knock Alejandro off of his platform, allowing her team to win invincibility. However, it is later revealed that Alejandro purposely threw the challenge.

While on the plane, Alejandro helps to hide Cody from Sierra because Cody attempted to vote her off in the previous episode. He also pointed mockingly at Sierra when Heather stated that her team does not get distracted by boys.

Initially, Sierra is supposed to be partnered with Alejandro, but she refuses. Right before he exits the machine, Sierra slams the door shut, crushing one of his arms. She then thanks Heather for taking him.

After the challenge ends, Alejandro pretends to be the witness of the "marriage" between her and Cody, in order to get her help to vote off Owen.

Once he knows that he is able to gain Heather's loyalty, Alejandro focuses on breaking the bonds between Sierra and Cody by inviting Cody to first class with him, infuriating Sierra.

Rapa Phooey!
Because of his actions in the previous episode, Sierra begins to hate Alejandro even more and calls him a "homewrecker". Upon finding one of his eggs during the challenge, she intentionally breaks it, and glares at him. Alejandro then retorts, telling her that he will remember her actions upon finding an egg in her color. Once Sierra discovers Cody and Alejandro have decided to work together for the challenge, Sierra is furious, telling Cody that he cannot align with Alejandro. Sierra eventually aligns with Heather in order to eliminate Alejandro, but is unsuccessful. Sierra and Alejandro both vote against each other at the fake elimination ceremony.

Awwwwww, Drumheller
Alejandro tricks Sierra that Cody is cheating on her with Heather using a fake picture of Cody and Heather cuddling and she believes it. It was not until Cody explains what really happened that she realizes she was tricked. Angered, Sierra manage to get Cody and Heather's help to vote him off.

Alejandro tries to warn Sierra as she brings out Cody's birthday cake in the oil puddle. After Sierra blows up the plane, Alejandro shows concern by asking if she is okay. The plan of eliminating Alejandro almost succeeded, but Sierra accidentally blew the plane up, resulting in her own elimination.

Like almost everyone else, Sierra supports Cody over Alejandro during the tie-breaker challenge and was furious after Cody was almost killed. In Heather's ending, she cheers for Heather after she kicks Alejandro in the groin and wins Total Drama World Tour along with the one million dollar prize.
