Fade knows what makes every agent afraid. We all know Chamber's main fear is the VP finding about his involvement in Fracture, and his deal with Omega-Chamber. But people also have suggested that he also fears being despised by his allies judging from the teaser, which suggests Chamber has actually grown attached to the VP, unintentional or not.

From what we know, Omega-Earth agents were the one who kidnapped Fade's friend, which is why she blackmailed the VP. Chamber having a truce with one of those kidnappers definitely is super suspicious, and very risky for her friend's and VP's safety. So why won't Fade tell Brimstone about Chamber, if she's supposed to be their ally? Is it because she thinks Chamber is still necessary for her personal goals? (Chamber did tell Brimstone that he is the "key to the other side") Or is she aware of Chamber's growing attachment to the VP, her included, and she thinks that Chamber will make the right choice when it comes to it?
