Marcus asks Will for advice on how he can get Hannah to invite him to her upcoming birthday party. When that proves unsuccessful, Fiona takes it to task with Joanne, Hannah's mother, who also happens to be the queen bee of a group of neighborhood moms that she is trying to win over.

With Fiona putting in extra hours at work, Marcus finally gets his own house key, but he quickly loses his mom's trust when Will has to rush him to the emergency room following an untimely incident with a knife. However, Marcus' misfortune has a silver lining for Will when he crosses paths with Dr. Samantha Lake, a beautiful and charming doctor who comes to Marcus' aid. Will is instantly smitten and stops at nothing in his attempts to win her over - even if it means bending the truth.
