Maybe I'm crazy, but if people are asking me about something that isn't happening, I don't say things like "We'll leave it at that." Especially considering the thing we're talking about is my current general manager's job security. If nothing were going on, I think the messaging would be far more plain, at least for Holland's sake.
Hmm, let's see how that line works elsewhere.
Patient: How long do I have left?
Doctor: I know we have you on the schedule until the weekend. We'll leave it at that.
Wife: Are you seeing other women?
Husband: I know my secretary is married. We'll leave it at that.
Child: Do you think I can grow up to be an astronaut?
Father: I know your teacher says you eat glue a lot. We'll leave it at that.
Yup, definitely a flawless line for all situations.
