Okay. Assuming Shiva is a Nexus (which I do), any Town aligned role that targets her will randomly target another player. A Town aligned player that does so will still learn something though it would not be what they intended to learn in the beginning. If a Town aligned player targets me, then they're wasting their time because I've already told you my role. It's up to each player to discern whether I'm lying or not but, from my perspective, they have nothing to learn from it. If something can be learned from a Town aligned player targeting me, please enlighten me.

We've already been over a Gunsmith. I would not have a gun.
A Watcher role could target me to possibly find another player with a night action that targets me. Unlikely.
If Titan targets me, then I would like to think I'd return a Sane result because I have yet to be recruited by a supposed Cult.
Cops will find me guilty.

Shiva also voted for Titan. That makes it...

Siren - 1
Titan - 2
Valefor - 3
