What a great episode. And after watching it, I have to say that it was perfect to put it before the next big arc.
Spoiler for Episode 20/Preview for 21:
I love the guild members when they're younger! Mako and Eri Kitamura crack me up as younger Natsu and Gray. It was also amusing to hear Cana admonish a younger Gray since they share a seiyuu. (I'm very easily amused) And I loved MiraJane and Erza going at each other (and Natsu calling her on the double standard of fighting). Ryoko Ono and Sayaka Ohara were perfect in those scenes. Elfman was hilarious as well.
Lisanna was absolutely adorable and I loved her straightforward attitude and how she always managed to catch Natsu off guard. So cute. I'm going to have to echo Shiroth on my favorite scene being grown up Lisanna keeping her family in line.
This episode just make me smile so much.
Next week brings my favorite character into the mix. The Phantom Lord arc is full of so many awesome scenes. I can't wait,
