5 things that will shock us in the next episode

What do you think those 5 things will be?

My list...
1 Desmond comes back
2 We learn something vague about the hatch that will raise a 108 questions.
3 Sayid Charlie and Angry-Lucia find the balloon, or not and are caught in a ambush. (hope for #2)
4 The hatch obviously goes wacko
5 Eko betrayed by Henrys lies asks for his beard stub back.
