Honestly, I can think of two episodes with minor build up moments to create an arc for this:


 * The Crystal Empire- Luna summons Starswirl the Bearded's book as the mane six take the train back to Ponyville


 * Keep Calm & Flutter On- Princess Celestia leaves the elements of harmony with Twilight after Fluttershy reformed Discord

& if you want, Magic Duel could also count as an arc episode because it shows how powerful Twilight's magic has become & how well she's seen the importance of friendship
