Angel was using the duo to infiltrate their home and use the computer's database to find rehabilitated experiments, all in order to hypnotize them to becoming evil again and bring them to Gantu so they can be brought to Hämsterviel. While she sleeps in a basket in the "ohana"s laundry room overnight (Lilo was unwilling to let Angel sleep with Stitch), Stitch wakes her up with a bouquet of flowers; she tries to convert him with her song from there, but only gets a compliment for her singing from him in return. She later runs off to convert several experiments to evil again, while Stitch tries and fails to gain back her attention. At night, she runs up Mount Waialeale with Stitch following her to meet up with Gantu in a spaceship ready to send experiments to Hämsterviel. In the ship, she and Gantu trap Stitch inside and release several experiments to knock him out. However, feeling guilty for betraying the one person who was genuinely kind to her, she sings her song backwards to convert the experiments back to good before Stitch gets pummeled, and they bring the spaceship crashing back down to Earth. Just as she and Stitch free the experiments, and Lilo finally accepts her into the "ohana" for her redemption, Gantu captures Angel as punishment for her betrayal towards him and runs off with her. In "Remmy", she makes a minor appearance in a dream sequence, as she was still under Gantu's captivity at the time of the episode. In "Snafu", while she was still captured, 625 tricks her into singing her song backwards to supposedly turn him good, secretly recording her so that Gantu can play the song in its normal form to convert the rehabilitated experiments back to evil again. However, the plan fails when Experiment 120 (later named "Snafu") steals and runs off with the recording. Meanwhile, Lilo and Stitch plan a rescue mission to free her and the other experiments that Gantu captured, but Snafu foils them as they infiltrate Gantu's ship. After Stitch professes his love for Angel, she breaks out of her containment capsule, frees Stitch out of his, and after hugging each other, they free Lilo and the remaining experiments. Lilo, Stitch, Angel, and the other experiments then escape the ship, and afterwards Stitch and Angel go out on a date.
