S3E12 "Par Avion" plot twist is the most shocking thus far!!!

I'm watching for the first time and just got to Jack and Claire being >!half siblings!<. I called it with about 2 minutes to spare and felt really proud of myself, but this is THE MOST shocking plot twist of the show so far to me. Michael >!shooting Ana Lucia!< and Libby >!being a mental patient!< are also up there for me.

When I get to the end of the season I'm gonna do a "thoughts so far" recap!

I politely request this thread remain spoiler-free for anything after S3E12
