Twilight has lost someone very important in her life. Bargaining is normal in the grieving process but fruitless as some pony can't just bargain with Death. Twilight however, isn't just 'some pony'.
A fan of ponies since the premiere of the 2nd season, a fan of TMNT for most of my life, and a writer with probably way too many ideas and not enough time to write them all down.
