I didn't like No Second Prances. The fact that Twilight didn't trust Starlight's judgment and wanted to damage Starlight's chance to gain Trixie's friendship felt really off.
Why exactly does Starlight deserve unwavering trust already? Can't really understand that. I think Twilight was perfectly justified in believing that Trixie might just be a negative influence on her.
@CC: Because Twilight and Trixie parted on positive terms. Twilight may not've forgotten, but she forgave, and Trixie changed. The fact that Twilight wanted to sabotage their chance of friendship makes no sense given past context.
