Shawn was just about ready to facepalm the hell out of himself. He couldn't talk to Jack with Juliet standing there and he couldn't talk to Juliet period. Because he had no idea what the hell he was going to say.
Jack shoved him and Shawn let out a silent breath, touching Juliet's arm lightly and nodding for her to follow him outside. Screw it - if Jack was going to Retcon her he'd Retcon her, so Shawn might as well come clean. Or try to, anyway. He still wasn't sure where he'd find the words for it.
