What if a cutie mark was not just related to a pony finding their talent but also a sign of a pony becomming an adult?

This was the question that Apple Bloom thought about after another failed attempt to get her mark.

But is her attempt to get her mark through magic going to work, and more importantly, what will the consequences of her actions be?

A dalek appears in Equestria - not just any dalek, but the one that had been corrupted by Rose Tyler's DNA. It has a choice of life as a pony, or dying, and finds that it cannot bear to die a second time. Thus begins a strange adventure as the dalek tries to find a place for itself in a world that is completely antithetical to its former existence and way of thinking...

...and why does that earth pony stallion look familiar...?
