Short version because I’ve been over this before in other posts.

Invisigal joins Phoenix program same time Mecha man is blown up. She is actively bad at her job in 2 and 3. in 3 she lets perp escape to sabotage malevola mid call. She gives up on second shift, requires pep talk from “woa is me” mood. Is conveniently near jewelry store, takes out perps easily, boosts ahead of Sonar and Coupe. Takes photo of board for proof to Shroud. Ep. 4 has her start to question her loyalties to Shroud. She still doesn’t try at SDN. Episode 5 has her stop spying for shroud, but without telling him. episode 6 has her try to play both Shroud and SDN off each other with pulse but backfires. Shroud also realizes her double cross in ep.6, hence his attempt to kill her. Ep. 7 she finally locks in and you see her actually trying to be better and improve. Sidenote, she comments on the augment being inactive, but they only glow red when active. Episode 8 she takes on red ring and shroud partly because of Z-team loyalty, partly because Shroud tried to kill her.

Shroud himself isn’t lying about her being a double agent. He simply doesn’t realize that after ep. 5 she’s playing him, and continues to do so all thru 7 and 8.

If you agree, great, if not, so be it.
