Give her a chance.

After waking Seamus, the mage is allowed into the group with a unanimous vote. She's registered as a temporary adventurer and the four of you take a line of credit with the guild to celebrate the union of your party with a feast. During the feast you get to know your party members more. Seamus was raised in a small fishing village, he spent a few years as a vagrant before contracting lycanthropy and becoming an adventurer. Ashera was raised by an overprotective father and had few friends growing up. Your new mage, Olympia comes from an affluent family, she's the third of five daughters. The four of you drink and feast until Seamus falls asleep at the table. The three of you manage to carry him into the one bedroom you could afford to rent. You dump him onto one bed, leaving only one bed open for the three of you. Your party decides it would only be fair to determine which two of you get the bed with a game of rock, paper, scissors. The loser will stay in the stable with Reuben.
