Assy first heal was only single, because he was on 25 and couldn't be double healed, and Scraw's vote was valid, since it says on top of the blog:

"No double heals for people above 25 health. If these happen then they will be classed as a single heal."

So the first vote by Assy is only +1, and Scraw's -4 is between Assy's second vote and GG's vote, which would mean that Andy killed Wach (as Bantha already said).
