>>115542484>would hit me better if there was any indication of SW feeling regretful of her treatment of them before that moment.There are several.
Micah shits on her throughout the season. Everyone does, but she is the one person she never defends herself against. She just takes his contempt, even seeming a little miffed. Regardless she keeps praising him to high heaven at every opportunity.
While in Mystacor she looks up at her own marred statue, as if in contemplation of what kind of legacy she's left.
Her response to Adora chewing her out was not her usual dismissals or rejections, but a solemn "I did what I had to do", even said with an inflection of hurt, like she couldn't understand why Adora was so pissed at her.
After they make their war plans and Adora declares her intent to go through with the plan SW herself proposed, everyone else cheers, but SW merely stands of in a corner sulking, as if none of this was pleasing or even made sense to her.
When Catra comes back to camp to find Adora, the only person left is SW, who in uncharacteristic fashion has decided to get sloshed while the world teeters on the edge of destruction.
Then finally watching her daughters carry each other through the tunnels she realizes their only drive is to protect each other, regardless of her attempts to separate them. This is when it hits SW that they are stronger together, an idea that is totally alien to SW, and that she is just an interference. Her talk to Catra about how "it's too late for me, but your story is just beginning" is her acknowledgement that her entire life philosophy of living only for yourself was a mistake, and Catra, someone who she has previously stated she sees herself in, has escaped the trap of thinking that way and invested herself in her love for Adora.
Shadow Weaver by the end realized she was a broken bitch that had no place in the world, and being the prideful asshole she is she chose to just end it instead of trying to fix herself.
