Blue Thunder was walking around Canterlot with you since you just moved to Canterlot to make new friends, see new places and to just live a more interesting life. He was also curious about you so what if...he could be your first friend?

Blue Thunder: "And that wraps up our tour. So say...would you like to hang out a bit after you get comfortable around here since I will want to know you more. We could even be friends."
