She was clearly a favorite of someone since she was so heavily utilized on RAW during the pandemic. I haven't watched RAW in a few weeks, but I'm guessing they realized what she brought to the table in terms of on-screen talent.
Ehh I think there’s also an aspect of embarrassment on her part since her firing didn’t move the needle like that and it essentially amounted to nothing. She took the fall while everyone else had no problem abiding by the new edict. It was obvious that they didn’t want to fire her, but was left with no other choice as they had to prove a point.
Come back and fall in line like everyone else did.
