(Please read description first) This is IB's best buddy Caliber: https://mlpforums.com/uploads/f706e16d6342606a31129620242629a9.png
They've known each other for about 5 years, and are about equal in combat skills.
Rarity on the other hoof, http://1.bp.blogspot.com/-IrxWMAAa59Y/VJcwMUclj1I/AAAAAAAAAYo/WrLGJd5dc9I/s1600/Tumblr_mxzwafbm7w1s88ss5o1_1280.png is IB's crush. He hasn't talked to her prior to the story, so it should be interesting how he goes about it. Throughout the story, Caliber will help IB overcome his shyness when he's around Rarity. Blizzard will also attempt to try an establish a relationship with Rarity. And lots of other crazy stuff, such as fighting, will happen in the story as IB attempts to break away from his shy self and confess his true feelings toward Rarity.
