#HateTriangle is the sixth episode of Season 1 of DC Super Hero Girls. It is aired on March 24, 2019 on Cartoon Network.
Just before Metropolis High's latest football game, Hal Jordan's ex-girlfriend Carol Ferris arrives on campus as a cheerleader for the rival team. Carol is still furious at Hal for the way he broke up with her, and she manifests her powers as Star Sapphire and targets both him and Jessica, thinking mistakenly that Jessica stole him from her. Without using her own powers in aggression, Jessica shows Carol the truth, convinces her of Hal's flaws, and tells her that she needs to love herself first. Carol leaves, but vows to make Hal worthy of her love one day.
