"...no matter how slim the chance is that he finds his brother alive."

Hi,
Yes, it is.

Thanks for your reply Clive. I was just wondering whether we have to use the subjective form of 'find' here.

Hi Clive,
Could you possibly explain why "that" is used in this sentence?
"no matter how slim the chance is that he finds his brother alive."

Is this natural?"

Thank you in advance

Is this natural?" I wouldn't say that you can't omit it, but it's more natural to use 'that'. You'll also often hear

"no matter how slim the chance is of (his / him) finding his brother alive."

It also depends on the register. In casual English, you

Thanks for your follow-up Clive. 

I wonder does using the subjunctive form of 'find' makes it seem more likely that he is going to find his brother alive or less likely. 

Thanks again
