Possible Spoiler Info--4 questions

Brian or anyone who can shed some light on the show for me,

I don't have the feeds this time, but have been reading this newsgroup.

1)  Tonight, 4/22 there is a HOH comp going on where Shiela, Ryan and 
Baller are on boards in the water.  This is part 1 of the HOH comp, right?

2)  Does anyone know what part 2 was and who won?  I think I am getting 
ahead of myself...hmmm...

3)  There is a Wednesday show tomorrow, but will there be a Sunday show?

4)  I read here that Shiela was taken to the hospital.  What for and was 
that for real?

Thanks in advance,

LC
