I like Starlight. I just think she's an absolute freaking dumbass and has a shitty backstory that doesn't make sense. Like seriously, Starlight, there's such thing as SENDING A LETTER!
Well, if Sunburst's folks moved and left no forwarding address, Starlight wouldn't be able to find him (although she obviously did track him down sometime during in the interim).
I wonder if this series will ship the two of them. Perhaps Twilight will have to make a rule about her student/houseguest sneaking in stallions after hours (perhaps after catching the couple in a, er, compromising position, or running into Sunburst in the shower one morning).
