These types of stories where people go to another universe always make me wonder: what happens to that universe's Eko or, more importantly, Heimerdinger? "Our" Heimerdinger has been there for 3 years, so was the other one just gone all that time? Was he aware but unable to act? With Eko it looked like he didn't remember. What if "our" characters just completely ruin their other self's life?
While I love to see Powder happy, I love our Jinx even more.
Also, what's with all the vomiting in this episode? I didn't need that.
