User blog comment:CutePets95/Who do you think's the mole in The Bureau?/@comment-78.172.120.211-20160714090245

Okay here are my guesses:

Ripley: She's not in the AI pic of Africa cases and SOMBRA made an attempt on her life so it can't be her.

Ingrid: Her appearences are quite rare and she was not present during Ripley's assassination in Spain. And she should have knowledge of tech, given that she's the administrative assistant. However she's not in the AI pic either but she makes a stronger suspect than Ripley.

Jack: We don't know his past profession and he'd been acting rather weird since we started Africa.

Carmen: Elliot said that she was the last person he saw near the control room when BOB was sabotaged. Although the mole was most likely trying to frame her since she's no tech savvy and couldn't have sent the message of the mole being discovered.

Angela: The least likely member. She's got kids so she cannot possibly be a SOMBRA member who'd been killing children.

Lars: Same reasons as Angela.

Elliot: He's the one who discovered the presence of a mole within the Bureau. He's been working hard to reveal them but it could be to avoid suspicion. Marina: Like Carmen, the mole could have been trying to frame her by removing her file from the files they dumped into the falls in Case 40.

Dupont: He was a Promethian once, which was the European branch of SOMBRA. He may not be a tech savvy but he's a smart guy. And his appearences are quite few.

Jonah: Already ruled out since the mole had been leaking information since the Bureau's presence in Europe and Jonah joined the team at the end of Sahara.

So my prime suspects are Ingrid, Jack, Elliot and Dupont.
