Justin, Katie, and Sadie

The Katie+Sadie-Justin Relationship is the one-sided relationship (on Katie and Sadie's side) and conflict (on Justin's side). The relationship, and conflict, was mostly seen in Total Drama, Drama, Drama, Drama Island!, as it was not worked in the second season due to the fact that Katie and Sadie did not qualify for Total Drama Action.

Total Drama, Drama, Drama, Drama Island!
Katie and Sadie formed a group with Justin, as well as with each other, to search for the million dollar case. Justin, in the beginning of the episode, enjoys the attention the girls are giving him, and begins talking to them about his modeling career and slightly flirting with them. However, Justin eventually tires of the duo's nonstop talking, and ends up ditching both Katie and Sadie by tricking them into spending the remainder of the competition in a cave. Even though Justin hates them, Katie and Sadie have huge crushes on Justin. They even get into an argument over who he likes better during their wait in the cave. In addition, the two girls seem to think everything of his essence must be beautiful, hence them saying things like "You don't think Justin goes number two do you?"

Total Drama Action
After Justin says that he would plan on getting back to modeling after the show, both Katie and Sadie agreed that he still has it in him. The three would later join Trent, Beth, Geoff and Eva into finding some help only to learn that the seven of them would not be returning for Total Drama World Tour.

Theme Song
Katie and Sadie are seen gushing at Justin in the theme song while he looks in the mirror.

Haute Camp-ture
Sadie and Katie are gushing over Justin (while he is diving of the diving board at Playa des Losers), and saying how cute he is, much to the annoyance of Noah.

Trivia

 * This relationship could be the Total Drama Island counterpart of the Katie+Sadie-Trent Relationship, as both relationships are one-sided on Katie and Sadie's part and Katie and Sadie fight over the male.
