The funny thing is that these two look like to characters that belong to . The pink one is named B* Dancer, and the blue one is Midnight Fun. They are sis...siblings. BTW, BD is also a guy, and MF is a girl.
Therefore, my first thoughts: Cadance, no! They're siblings!
For me there are two reasons why I think this is funny:
1) The shadows on her face make it look like she has camouflage face pain on, trying to be all sneaky like in her goals. 2) In my headcanon she is part of the Guard and is one of the finest sharpshooters in all of Equestria.
