since Emily Deschanel told me Booth and Bones would be in bed together, I had to dig a little deeper. Turns out, it could be a trick! Taylor says, "They've been toying around with interesting ideas about alternate realities, where perhaps they're married, where we're all in interesting, different roles. So we may get to see it, but it may not be real."
