I thought she had trained with Yev over the course of the timeskip? That didn't improve her skill? As for growth, that really happens as we develop backstories and character interactions. That's why I was trying to talk with you a bit via PM about Aqua's past-- to help you develop her and give her more to work with.
Aqua didn't grow or change. Aqua got interrupted when I tried to do any. Just when I was starting to do some grow you timeskiped over it. I know I don't post the most here. I do take fault here, but I've just had bad luck. By the way, it seems like the whole flank thing is starting to be useless. It seems like people are all over the place. If we could get a map to mark where players are that'd be helpful, but I understand you can't.
There's really nothing I can do about the timeskip now. There's a lot of characters in this RP to consider that I can't postpone too much for one character. Not saying that it's your fault, but I hope that you can partially see where I'm coming from, too. I don't feel like we're helping anything by rehashing this, but if there's anything we can do going forward that would be something I'd gladly help with.
And no, the flanks are working just fine. Everyone is still in the flank that they started out with. I'm not sure why you thought that they are all over...? Unless you're talking about Rabiyu, Alastor, and Henry, who are special cases between flanks and can challenge either center or left of Kilkis Seres.
