I can’t really recall any episode from Season 3 where Pinkie Pie was following Twilight Sparkle while talking fast. Â
The closest i remember was the interaction they had in the beginning of the third episode Too many Pinkie Pies.

Where were they in the scene?

The only time I can think of Pinkie talking really fast and following somepony was in the first episode when Pinkie was following Twilight in her house and talking really fast.
