Salu Digby/ Shrinking Violet

Colossal Boy was finally able to act upon his unrequited feelings for his teammate and the two apparently became a romantic couple. The relationship developed fairly quickly, and the two were soon married. The pairing was a surprise to almost everyone, as she had been previously linked with Duplicate Boy, a member of the Heroes of Lallor and one of the most powerful beings of the 30th century. When Duplicate Boy learned of the relationship, he tracked the couple down and proceeded to beat Colossal Boy mercilessly until he realized what no one else had yet deduced: the woman involved with Colossal Boy was not Shrinking Violet.
 * 1)  Ord Quelu / Duplicate Boy  - Salu was involved with this member of the Heroes of Lallor, one of the most powerful beings of the 30th century.
 * 2) Gim Allon / Colossal Boy - Salu's fellow Legionnaire was infatuated with her, and it's possible she reciprocated to some extent, despite her relationship with Quelu.

In reality, Shrinking Violet had been kidnapped by radicals from her native planet Imsk. She was replaced in the Legion by Yera, a Durlan actress who used her native shapeshifting abilities to assume Violet's identity and mimic her shrinking powers. However, Yera was an unwitting pawn in the plot, as the radicals had told her that Violet wished to go on a secret vacation.[2] When "Violet" became involved with Colossal Boy, Legion deputy leader Element Lad and Science Police liaison Shvaughn Erin became suspicious, particularly since "Violet" was seemingly cheating on Duplicate Boy without trying to hide it. Along with Brainiac 5 and Chameleon Boy, they were able to expose Yera as an imposter, and rescue the real Violet.[3] However, the passion between Gim and Yera was genuine, and he remained with her despite the initial deception.

Shrinking Violet harbored resentment toward Yera for years, despite the fact that the Durlan had been duped herself. In the "Five Years Later" version of Legion continuity, Violet finally forgave Yera. Yet these events have since been erased from continuity, and the two remain at odds.
