In Seven Psychopaths Charlie (Woody Harrelson) comes to the hospital to find Mrs Kieslowski. He finds a patient- who we know is Myra Kieslowski- but wrongly assumes that because she is black it cannot be her. He then tells her how he is looking for Mrs Kieslowski because her husband has stolen his dog.
In the course of the subsequent conversation, he comes to realise that she is the woman he's looking for. But I can't understand how.
Here's the discussion between Charlie and Moyra.
Myra: I'm sure Mr. Kieslowski will take good care of your dog and get it back to you safe. He always seems like a sweet man when he comes in.
Charlie: He come visit her a lot?
Myra: Every day-
Charlie: What kind of times every day?
Myra: Different times, you know. And not every day. He misses a day now and then.
Charlie: Oh. yeah? He been in today?
Myra: Yeah. He came in earlier this morning, about 10:00 or so.
Charlie: So the Polack married a n*gger, huh?
How did Charlie deduce this, from the conversation?
Was it just the fact that Myra seemed too eager to convince him that Charlie had already missed Mr Kieslowski's visit and was wasting his time waiting? In which case, why did she say he visited every day?
