Jetta follows Pizzazz's lead when it comes to picking on Stormer (The Bands Break Up). However by the time Roxy leaves the band, Jetta is just as worried as Stormer and the two team up to follow Roxy despite Pizzazz's assurances that Roxy has nowhere else to go and will return to the Misfits (Roxy Rumbles). When Pizzazz becomes obsessed with Riot, Jetta, Roxy, and Stormer are disgusted by her behaviour, allowing Rapture to make a fool of her, and mooning over Riot like a lovesick girl. They confront her and walk out on her, despite the fact that Pizzazz is the Misfits (The Stingers Hit Town).

Jetta lies constantly. To the press, to her friends, any time she mentions where she came from or what connections she has, chances are, she's trying to palm herself off as better than she is. Particularly when to comes to taking advantage of naive Americans who see all English accents--even working-class London ones--as "posh." Whether it's her close personal relationship with the Royal Family, or her own parents lands and fortunes, Jetta has a habit of engaging in hyperbole to try and make herself seem important in the other Misfits eyes, particularly Pizzazz'. While Stormer buys it hook, line, and sinker, and Roxy thinks Jetta is nothing but a fraud, Pizzazz seems amused and willing to be convinced. However, during a trip to England during which the entire Burns family are used as pawns in an attempt by Mason Hawthorne's uncle to kill his nephew and inherit his estate, Jetta is caught out in her lies regarding her background (Britrock).
