Where a Season 2 could go...
Of course, Starz has already stated that a Season 2 is unlikely, so this is just a list of speculation (and SPOILERS) based upon the aftermath of Season 1...
The consequences of Bryan's murder, which would probably be assumed to have been the result of a robbery. However, Romeo took Bryan's backpack.
The Russian strip club owner now essentially "owns" the ballet company. What could be the consequences of this?
Mia presses on, despite her MS, to try to get as many good remaining years out of her career before the disease forces her to retire.
Kiira becomes pregnant? Would she still be involved with the ballet company, perhaps serving as a mentor to Claire?
What becomes of Claire's father? Would Claire put him into a nursing care home, and how would she pay for this?
Would Claire go back to stripping (to help pay for her father's care, for example)?
What is the situation with Claire's mother? Is she still alive?
What will the ballet company do for its second season show?
