From my list, here are my choices:
A) Martha has a drinking problem. Ellen, Sarah, and Jack hold an intervention for them.
B) Penny has been set up on a blind date with Zara.
C) Jimmy and Penny go to see a play that Ching is performing in.
D) Jonathan and Perry are mistaken for a couple.
OUCH!! I actually think that "D" is the most plausible...lol!!
