I could not make out if the new leader was 1st in command on the ground, the watch commander or the head if the entire unit.
If it was first in command on the ground (probably not correct term), I would say someone was being punished for trying to help.
Otherwise, someone has already been designated the guilty party.
Of course the possibity exists this person raised holy hell because the unit was told to stand down. Dissenters are not tolerated.
