Since this is going to be used out of context, my ability just let me see 3 actions and who they target and decide to stop them or to let them through. Can't pick and choose though, either all go through, or none does.
So I had to choose between a Kill on Kerko going through + a Lie Detect on Ratchet, or if I should stop them both (last one was the submerge one which let someone travel faster)
Since I got scum leans etc on Kerko I decided to let them all through
