Anyway, while Frank alternated between freaking out and stewing, Micro started training a new Punisher (

When Frank escaped, he was pissed and went after Micro. The two fought, and it's left ambiguous as to whether not Frank (who inevitably won) would have killed him since the building they were in was blown up by a psycho S.H.I.E.L.D. agent, killing Micro while Frank was seemingly struggling to pull the trigger on him.
