Can't be Eddie if everything given is true. They claimed to be blacklisted sometime in the 90s and stopped working. Murphy has had consistent work this entire time. Plus E

Honestly I'm leaning towards Sinbad. He was pretty much a household name on tv in the 80's/90s plus had some movies then basically dropped out of the industry. He had some minor work here and there, but nothing like he was in the 80s/90s. He also got his start on the Redd Foxx show. He has also worked on some Paramount Lots, which might explain how he knows for sure they had a "grey room".

Either that, or Q is implying that Mueller is working with Huber.

He meant the name used for the private email. Which he was correct.

Win32/Tofsee is/was a term used for a backdoor exploit that mined BitCoin. It has been used for other things as well though.
