Shortly after Finn fails to follow Ren's instructions to "kill them all" (the villagers at Tuanul on Jakku), we see Phasma tell him to "submit his blaster for inspection" and "report to [her] division at once". Is this just a standard after-action procedure for all blasters, or did Phasma suspect that Finn failed to follow orders, and was having his blaster checked to somehow verify this suspicion?
It's not clear if the impending discovery of his failure to follow orders, or simply his disgust at the events on Jakku that just transpired, or both, lead to his decision to escape with Poe.
Can we assume from Phasma's request and Finn's reaction that First Order blasters maintain some sort of record of when they were fired, either explicit or implicit?
