They apparently lay on their bellies by the monitor like a kid's sleepover watching TV. This is all per Mox's book I've been reading.
He also sheds light on Kevin Dunn and just the BS nonsense created by the egos of those in power. Told a story about how when Ambrose was US Champ back in 2014 (?) that he got called into the production van by Kevin Dunn ("the guy responsible for the nauseating quick camera cuts that probably give your kid a seizure"-Mox). Two days after the PPV, Dunn calls him in and shows him video. Ambrose can be heard "Give me my f___g belt" to the ref. Considering the ring is mic'd, you're bound to pick stuff up. Anyway, Ambrose is really repentant, apologizes profusely. Gave a hearty handshake to Dunn who was sooo nice to him and Ambrose left feeling good about the meeting.
Not long after, Michael Hayes passes Ambrose in the hallway and says, "Wellllll, I don't think that was the right kind of apology for the push we want to give you." Ambrose was confused because he thought things were good considering how they left it and how nice Dunn was to his face.
Said one line by Dunn or interpretation by him and he can alter your career and apparently has to former wrestlers. "That's a lot of power and that power breeds go. Connecticut, old rich boys club ego."
Pretty good insight in why people grow to hate the mothership.
