If Blade is a wolf, there are two options:
1) You and Blade are paired and are the remaining wolves.
2) There are three wolves remaining, in which case we are somewhat screwed, of which you and Blade are two of the wolves.
There are no other reasonable options for Blade to use the 1/game redirect to save you and kill Jeen. I buy that Blade would bus a wolf for cred; I don't think that he would use a 1/game power to gain cred unless it was W/W wagons. So the chance that Merel and Blade are the remaining wolves is unlikely.

I also think it's unlikely that Flat gives a five-wolf team a vote hijack; I buy that much more with four wolves. So again, very unlikely we have to worry about both Blade and Merel being wolves.
