After convincing Valerie that she can be trusted alone, Erica disappears with all of the gang's valuables. David turns to a loan shark for help with his money problems. Donna discovers that David forged her name on a check. Torn apart by David's deceitful actions, she dumps him and throws him out of the apartment.

A woman whom Steve dated over the summer shows up and claims that she is pregnant with his child. Noah refuses to accept Val's apology and resume their relationship. He gets very drunk and is arrested in a bar fight. Brandon bails him out, and Noah explains that it is the anniversary of the death of his fiance, Beth.
