Friendship is Coffee: I Like My Mares Hot and Dark

Twilight Sparkle seems to prefer Rainbow Dash to coffee. Perhaps Trixie can show Starlight why.

Twilight Sparkle's proclivity for coffee had been the stuff of legends, but lately Rainbow Dash seems to have convinced her to kick the habit.

Starlight Glimmer can't quite put her hoof on why, but her best friend Trixie thinks she knows the answer and is more than willing to share.
