You want to know? Several reasons come to mind:
1) I hate powerful JL's. They literally ruin the game for every villager that's not in them. Since I always complain when I'm a villager, it would be hypocritical of me to do that very thing as the priest.
2) The village was going fine without our co-operation. Very fine indeed. We had got several baddies killed and more were in the pipeline even without any further seer scans. This game was perfect for vote analysis but nobody really tried it AFAIK, except for wolves who done some token analysis that, if anybody had cared to closely scrutinise, would have been shown to have several inconsistencies. I'm pretty confident I could've got a couple more obvious wolves lynched just by looking at the votes, so could anyone else who might've been bothered. I inevitably got hunted and so couldn't do that, but once I die it's no longer a concern of mine.
3) Johho was not cleared. Remotely. He was unlikely to be a baddie, but easily possible. No reason for me to potentially throw away my life when, at the time, the village looked favourites to win. If the village was in dire straits, then I would've, but no we were going better than fine at this stage.
4) I did get in contact with you a couple of days afterwards anyway, by which stage the village was still doing great.
5) You clearly had already people in the JL that you chose to trust. If there's a tight knit JL I understand the wisdom in double scanning someone to absolutely clear them (although they can and sometimes are turned on the very same night anyway), but you had given away your role to two unscanned people and so there was no reason to actually co-ordinate our scans in that way. I still do not why you told randy you were the seer...even if he was good, why was there any reason to tell him? Couldn't you have said you were part of the JL or something? Maybe an SA villager?
And no, you still weren't right to trust randy, even if he turned out to be a goodie at the time. In the same way that it's not a good idea for a small child to accept a lift from a stranger, even if they are in fact just being helpful. The point is it's an unnecesary risk - You had no need to trust him! You only need people in contact whenever you have wolves to out, and even if you have one wolf that can wait a while.
EDIT: Wait...
WHYYY?!!! Heck, even if randakar had been doulbe-scanned I still wouldn't have done that.
However, it was very unlikely for you to scan Taklagarn that night, I grant you. However it may not have done any worse. At least as your apprentice you knew him, whereas if he became the priest after I died, you two could only have got in touch through the unscanned wolf randakar.
@reis91: Yeah that was taking the piss. I did assume you knew I was the priest, not because of the SA claim, but because you outed yourself after I applied some small pressure (I did suspect you before you were scanned). The fact is, as an active goodie I just don't survive werewolf games no matter my role.
@the_hdk: I didn't read the rules and actually did assume apprentices could be re-took, but after reading them it's fairly clear that it shouldn't have happened.
