Well if you blocked iLTS, you have a guaranteed nightkill, but Category 5 brings back KY (I assume), and we're back to where we started.
If you blocked Category 5, it's the same deal unless you manage to WIFOM iLTS and get a nightkill. If you chose this route, then Irish must have asked iLTS for a night action as well. I don't believe either of you have NK protection, so whatever I do shouldn't matter.
