I wonder why people dont write in this topic. I think its very cool sidestory.
+ i love Polly, she's pretty, deadly and we can see her as an teenage arrogent gank leader, and also as caring adult woman. About pretty - i think she looks better than May, Bern and Regina.
The fun part is Bern would actually like to be with her if there wasn't her/maytag relationship. I have a feeling there might be funny story there later. After all, the only one who would opose "open relationship" is Bern. May wouldnt giva a damn if Bern didn't.
I have no idea how ball thingie works. Blackbird doesnt seem to be a sorcerer. If it is a magic item - anyone could get one, and probably many people would wonder around with those. Also i dont see the possibility of her using it with mundane methods. So magic? But how did she get it?
+ Nobody ever stole it while she slept. This would imply there is some connection to her.
