In this episode we get to see the process of summoning and contracting a Celestial Spirit thank to Lucy, who summons a "spirit pet," a Nicolas variety (looks kinda like a cute little snowman) that she names Plue. After that, Natsu and Happy get Lucy to join them as part of their team within the guild, and they take on their first job.
The animation has remained consistant from the first episode, which is good-- it'll probably never go super high-caliber, but if it doesn't drop off to QUALITY! over time, that'll be very nice. I wonder how many episodes they're planning to do? The story follows the manga pretty closely so far, and this is our first two-part episode so far.
