From Anon...
Anon, take both my hands. Now jump up and down with me, shaking your head from side to side HARD, until the Extreme Shipper brainscramble is dislodged. You good? The REST of us who do not suffer from ES BrainScramble, ESBS for short :-), knew Cait simply meant she and Sam are comfortable with each other after playing a married couple for so many years. And even Sam said "bickering" like an old married couple. Nothing sexy or romantic about it, despite what ES have "read" into it.
So, let me remind you of REALITY, since some of you keep getting amnesia about it: REALITY: CAIT IS ENGAGED TO TONY. There is NO getting around that. Please try to let that bit of FACTUAL info seep into the dark recesses of your Extreme Shipper mind once in awhile. I promise it won’t hurt, and you just might like it. Reality–it’s nice once you give it a try. It only hurts the first time. This time it’s true. No, really. I promise. ;-)
