Actually, I like both ships. The things is Kate and Sawyer are very similar: even in love they can't decide. Kate is allways pending between Jack and Sawyer and Sawyer between Kate and Juliette. Uncontrarly, Jack was allways with Kate,even when Juliette was trying so hard to get to his heart.
I've seen almost all these actors in different things but don't remember all names. But the most popular I think is Michelle Rodriguez. She played in many movies including Avatar and,yes, Fast and Furious
I am at SE2 right now and I feel like is the time when mistery becomes deeper and bigger, but I am looking forward and I hope it will come the time when all gaps will start closing and things will become more clear. Unfortunately, from my experience with other fantasy/Sci-fi shows this is not really happening. They are makeing a bigg "mess "during few SE and then just wrap-up everything in last few min. of the last ep. And this is why many people feel disappointed because they have big expectations. And also somehow is true that most(or all) these shows have made up actions as we go, cause during all these years many things changing and they have to adapt action to the new situation. I've seen it in other shows as well, when actions from first seasons does not make sense later on and auditorium is lost and they missunderstand situations and are missleaded. So,it's something common.
