To this point, 'Ringer' (Tue., 9PM ET on The CW) has mostly been Bridget's story, with the occasional crytpic jaunt to Paris to check in on her twin sister Siobhan. Quite frankly, at times it's looking like Shiv is trying to kill her own sister, but maybe that's what they want us to think.
One thing that may have slipped our radar, or maybe we just assumed she already knew, was that Siobhan was pregnant. Remember now everyone thinks Bridget is and she's kind of playing along.
Well, when Siobhan suddenly got sick while scoring with some random dude, she took a pregnancy test and realized what we'd already known. Will this throw a kink in whatever her plans are. On an impulse, she even called Henry -- the guy who's not her husband that she was sleeping with -- but didn't say anything.
