From my knowledge:
-In the present:
She's going to be available in MC, and on Pixilart. But she will take a break from Imgflip.
-In the future (HEREWEAREINTHEFUTURE REFERENCE?!):
She might return, but it would take time (a lot). If she returned, she wouldn't be the leader, or an owner here (max number is 5).
Personally, she was a really good leader of this stream. The stream feels different now that Flare's the leader, but I think I would get used to it sometime. She would still be the "Absolute best user on the stream!" for me though, and for the entirety of this stream, she would mostly be the same as above, and an important member of us. I would NOT force her to become the leader again, because it would be stressful for her. I would NOT want her getting mentally sick again.
