Something confuses me about this film

Great film but one thing I dont understand when (Wu Bai)Jack's pregnant wife goes to get the money from the locker she clearly doesn't know (Nicholas Tse) Tyler she asks if he is one of her fathers men. And yet Tyler drove Jack and and his wife earlier and film and they were talking together at the drug store before bumping into the lesbian he got pregnant.

Was she in such distress and pain that she didn't recognize him? Or is this a film making goof?
