S1·E2 First Time

Merrill and Genie scold Louie for crashing Melissa's ceremony, but with no other magician recruits in sight, Melissa reluctantly accepts him into the group. The four head out to the ruin, although Louie quickly finds himself doing more manual labor than magical spells.

Despite the girls' initial misgivings, Louie does manage to open the entrance to the ruin with his magic. The party realizes, when they get inside, that any treasure which might have been there has long since been looted. In its place, they find a nest of angry goblins.
