Michael drove Monica back.
When Monica got out of the car, Michael expressed how grateful he was to her again.
Monica smiled in response. Compared to her divorce from Finn to help Michael, that was nothing.
With that, she said a few polite words in return and walked into the neighborhood.
Michael looked at Monica's back, and the smile on his face disappeared instantly. As he drove, he made a call. "Investigate Monica's cousin for me."
"Yes."
"Find out if she really likes Finn and how much she likes him!"
"Yes."
After giving his instructions, Michael hung up the phone.
The only way to make Monica give up on Finn was if Finn was already with another woman.
