There's only one question I don't see a logical answer for, but let me expand on my thoughts for why Robz:
Watno isn't a tracker. He's a backwards tracker. This is an important distinction. He targets people (let's call the X) covers them in paint, and then can tell who targeted X by examining who the paint spread to.
In this case, he supposedly targeted Jorbles and Insomniac - but for whatever reason, hit Robz and Insomniac.
So 2 people are covered in paint. Now along comes CF, all nice and clean. He walks up to Insomniac, says "Yo", and strangles him - in the process getting all this fresh paint on himself. As such, he's easily viewable to Watno, and Watno reports this to us.
Sadly, that is ALL Watno sees. Nobody else has residual paint on themselves.
Now, here's Robz. A proclaimed flavour thief. Covered head to toe in paint already. If HE went and targeted Insomniac, nobody would be the wiser. But what he claims is to have targeted Watno. Here is Robz' (belated) PM:
Flavour name: KELPtomaniac
Role name: Thief
Alignment: Town
Abilities:
The Seaweed life is a hard life. Stuck on the bottom of the ocean (or lake?) floor, it takes everything you have just to survive. But whatever your troubles and pains, you always held your head high and reached for the stars above the waves. And the sunlight. Gotta love that sunlight. Of course, whenever you are able, you are happy to lift a little extra from the chumps (and the chum) around you.
Each night, you may target one other player to steal something from them related to their flavour. Depending on the target and what is stolen, this may have additional effects such as roleblocking them or granting you a 1-shot ability.
You may save stolen items that give 1-shots, but you can only carry one of each (no saving multiples). You can only use one 1-shot at a time, and you can’t steal on the same night that you use a 1-shot.
So if he targeted Watno, what did he steal relating to Watno's
flavour? Was Watno Roleblocked? No. So did Robz gain a 1-shot? Not that he's claimed. So I have trouble believing this claim to be accurate.
More than that though, what logically fits is that he stole
Joth's flavour, and used it to kill Insomniac. He wasn't seen doing this because he was already covered in paint. As mentioned in my first sentence, the only inconsistency is how Robz got covered and not Jorbles. The first thing that jumped to my mind there is that Watno targeted Robz, and not Jorbles, to cover his tracks. But there are certainly other options (like perhaps Jorbles/Robz were busdriven).
The simple fact that Watno claims to have seen nobody else covered in residual paint points either to Robz or him - or both - lying.
