>>138599536I'd imagine that episode starting with Jess overhearing people talking about how Poison Ivy has turned over a new leaf, and it's all thanks to Green Lantern. Jess would be overjoyed to think that her efforts have finally gotten through to Pam and goes to tell the girls. Where the girls would be doubtful over Ivy becoming a good guy, least of all through Pam's constant rhetoric towards her. But she'd stick true to what she says and would like to go congratulate Pam about it. There the episode could go one of two ways.
Either
>A: Jess goes to greet Pam and treat her all buddy-buddy like about the news that Poison Ivy is a good guyor
>B: Jess turns around only to see Pam with Hal JordanEither way once Jess finally talks to Pam, she's confused as to why Pam keeps on showing her typical lack of enthusiasm while not getting the hint that she's uninterested and annoyed with her. Only for Hal Jordan to come into the scene and be accussed of interrupting Jess' talk with Pam, only for Pam to actually lighten and be openly posutive towards Hal, much to Jess' complete shock.
From then on, Jess would continue to observe Hal and Pam actually being friends throughout the day. Culminating in Jess finally seeing Poison Ivy in action. Whereas while stopping a crime-in-progress, Jess is about to assist only for Pam to call out to Hal Jordan for a tag-team as they both save the day. Making Jess finally realize that the Green Lantern who made Poison Ivy turn over a new leaf wasn't her, but was in fact Hal Jordan this entire time.
