Episode 5 Discussion [rewatch]

[Silktie]

I'm confused about something, though (I know, it happens quite easily with me!). In this episode Tessa suddenly mentions something about a deep cover operation to Zoe, intimating that her little money making scheme is in fact part of a secret op. But nothing like that was mentioned in the last episode, was it? Did they retro the story, or did Tessa begin to suspect that Zoe might snitch on her?
