It's the question on the minds of all Castle fans:

Will Rick and Kate take a break from investigating crimes in order to investigate one another's nether regions between the sheets?

Earlier this week, TV Guide posed this inquiry - or something close to it - to star Nathan Fillion. His response:

I teasingly say we're gonna risk it and put them together right away and see what happens. But the reality is when two people actually meet and are attracted but are perhaps not a perfect match, they've got to get to know each other. They've got to spend time with one another. You've got to spend time with someone. You've got to see what their decisions are like on a daily basis. I think that's why long-distance relationships don't work. Because you have them on the telephone.
