Why did Merrimen's girl tell him “I did what you told me” after sleeping with Nick?

Question

In Den of Thieves Nick went to a club and went to a hotel with a woman, who I think has a relationship with Merrimen. The next morning Merrimen randomly walks in on them, the woman flees, they stare each other down, then Merrimen leaves.

Afterwards, Merrimen's...wife? says "I did what you told me to". What did she do, just get his number so Merrimen could call him while he was robbing the bank?

Bonus question: Did Nick know the woman was related to Merrimen since he saw her at the hibachi restaurant with them?

Answer 1

In addition to getting the phone number, she also told Nick which bank they were going to hit. Merrimen wanted to make sure they were set up and stalled outside the bank, that way they could hit the Fed without Nick and the other LA County Sheriff deputies getting in the way.

Bonus question: Could honestly go either way. Girls in a strip club, especially with alcohol involved, look way different than they do in the light of day and more natural lighting. But Big Nick also could have done his research and already knew she worked at that specific strip club (thus the reason for him being there in the first place).
