Now that Part 2 is almost over, do you think he was a worthwhile addition to the cast?

>temp position
>temp to permanent is same time frame I'm to get married
>love job, pays well, etc
Whats the odds they don't take me on as a permanent position because I disclose I'm getting married in 2 months? Its two months time but the timing is sketch. Ideally I'd like to get hired on and start working at an assigned time after. I've gotten advice to not tell them until two weeks prior after getting hired on. What should I do HR managers?
