First, I'll try to piece together what's known about actions Night 3:

BlackAdder killed Talic (killed in the same manner as Isaac - bite marks; BlackAdder was a vig)
Talic roleblocked Kylia Skydancer (party invite sounds like a Captain Morgan sort of thing - plus Kylia said she was roleblocked and Talic was a roleblocker)
Beetnemesis was killed by ??? (burned to ashes, so look for a fire-wielder)
BlackAdder was killed by ??? (headshot, cleanly cauterized, suggests a laser of some sort)

So with that in mind... I think the NIPZ either killed both beet and BlackAdder (due to some sort of event that gave them a revenge kill for losing their Godfather Isaac the previous night), or we have a limited shot vig who killed someone, or... something else. In any case, it does seem that the two kills were done separately (i.e., not by the same person).

Also, going back to the flavor, the mafia group is called Ninja Pirate Zombie Robot Monkey. Is is a coincidence that Isaac was from Teenage Mutant Ninja Turtles and Talic was essentially a glorified pirate? Perhaps it's a stretch, but it could pay off to keep our eyes peeled for any further clues.

So, let's try to look for the killers


OK, so not much is known about this guy. He won't give us settings so he'll always be a possible culprit in pretty much any scenario.


Yea, so Star Trek and Halo both use laser guns. Definitely could have killed BlackAdder


Not really any lasers here unless she is Mecha Streisand from South Park (a Robot). Dexter's lab has robots, right? The others don't really have anything incriminating at this point.


He also claimed Star Trek, so he's a possible killer of BlackAdder. Sonic has Scratch, Grounder and Robotnik (evil Robots). He's on my suspicion list anyway. Don't really see any fire wielders, although I don't know about aSoIaF


WoT has people who channel fireballs and Greek Myths have all sorts of things, but it seems that Yuna gained control of Hobo's role at daybreak (so couldn't have killed anyone overnight)


Claimed to be roleblocked. I don't see any reason to doubt that at this point, I'm going to assume she wasn't the killer and that she is also not a NIPZ (no sense in roleblocking your teammate)


Yea, no comment from me


None of these has flame wielders or laser guns.

-------------------------------------------------------------------

In the end, I have to say, Blaine/Kronin 2.0 looks pretty suspicious (Halo/Star Trek), as does Fox and Ravens (Star Trek, Sonic Robots), based just on this character info and the info rana gave us about methods of killing. Fanatic-Templar is also a possibility. He could be the fire-wielder who killed beet last night, by process of elimination. I suppose Darth_Katie could have done it as well (Mecha Streisand from South Park), but it seems less likely, and honestly, if she really is Babs, I think rana would have written something other than just "cauterized headshot" as the manner in which the victim died

Now, the final piece of the puzzle is looking at how these people interacted with Isaac and Talic on the previous days, how they voted, etc. That could take a while...
