Well, given that the Necron tatoo is a self-destruct device and that Skellebro knew of that from other life, shouldn't he be more careful in NOT mentioning the Necron society until he gathered the intel he wanted? Just sayin' ... it is the second time he fails to get intel from a prisioner because of that :/ Let's just hope he ( or most likely crow!Isaac ... he is the one with a good head on his shoulders after all ) had the presence of spirit of tracking that guy that went straight to the Tower, because he surely knows things.
Also, F for Oscar. Probably the less deserving of dying at Skellebro's hands up to now.
