yes I know that this is not from TGH but I couldn't resist (they were to cute) and I know that this hasn't been confirmed by anyone, but never mind lets start, its like a brother sister relationship but I think it really grows from chapter 7 in broken love (a awesome series by the way) to being a start of something starting with Whisperfrsot blushing if Alderflare looks at her and in his mind calling her feathers pretty, this is also pretty strong when Alderflare comes out of Sparkleblossom's trance and seeing like how she really is. Whisperfrost also seem to like Alderflare back, being angry at Sparkleblossom.
