As you all know Spike finally let go of his crush on Rarity when he was still 11, he stop visiting her, talking to her, helping her out at her job, and being her little Errand boy. This proves Spike finally moved on, although Rarity do miss having him around all the time, but Spike doesn’t want anything to do with her anymore since she led him on and took advantage of his feelings for her.
Spike found new love, and this time it’s someone his own age.
Note: I haven’t drawn the Mane 6 yet so the Rarity in that picture belongs to Mauroz, check out his F.I.M Comic.
