Twilight just smiled and let Spike lead the way to the Ponyville market, there was sure to be something there that he thought was perfect, at least she hoped so. Considering what a big crush Spike had on Rarity, it was possible that nothing would seem good enough to him. However, no matter what Spike ended up picking out, Twi had a good feeling that Rarity would love and appreciate it just because it was a gift from Spike. Twi quickly decided against pointing that out because finding a perfect gift was very important to him and she didn't want Spike to get the impression that Rarity would just try to be nice instead of really love the present. Twi's thoughts were starting to get a little sidetracked and she was thinking about all sorts of different presents she'd given to ponies in the past. Just as she was worrying if Princess Celestia didn't really like the book that Twi gave her as a present last year, Pinkie seemed to jump out of nowhere and give her a hug. A little startled, Twilight let out a little "Eep!" before realizing it was just a Pinkie hug. Before she could even apologize for her startled response Pinkie wanted to start singing, so Twilight did what she always did when Pinkie wanted to start singing, smiled and nodded. Once Pinkie decided that singing probably wasn't the best idea in this case, Twi just hugged her friend and nodded again "Probably for the best, we can sing about it once we find Spike's perfect gift!". As for Pinkie's disguise idea or Dash's talking to Rarity idea... Twilight didn't have a good answer. So, instead of saying anything Twilight just turned to Spike, smiled and said "Well, it's your present, so this decision is on you, boss".
