Withdrawal - S2-E1
Revealing mistake: At 46:24, Peter and Mozzie are sat on a bench. Peter's paper has the exact same wording on back pages as well as the front page. (00:46:24)
Other mistake: When Neil is in prison and has time on his hands, he puts pieces together that were shredded. Neil's name in the file is CAFFERTY, not CAFFERY. Also, in the same scene, the words "e've" can be seen with the W missing. Yet, later on, when Neil shows Burke the final photocopied piece, the W that wasn't there is now visible.
Factual error: Mozzy plugs a laptop into a PBX switch in what can be assumed to be a server room. Somehow, this remarkably grants immediate access to security cameras and elevator controls without so much as an internal IP address or any administrator login access. This is ridiculously erroneous as no security camera or elevator control would even be accessible from a PBX data line, as these are only able to pass voice/phone data and nothing more. (00:27:40)
Character mistake: When talking to Felix at the planetarium, he correctly states that Tycho Brahe's birthday is December 14, 1546. Later inside the planetarium, Felix says they are looking at the sky on Tycho's birthday, but then says in 1592. (00:18:20 - 00:19:05)
