Alright, let's look at this from both of the other perspectives: Scum!LL & Scum!Swan. It's important to note that in all cases, Gkrieg knows who the scum team is.
____________________
Gkrieg's first post of the game could definitely be an attempt to tip scum!LL to his identity. I would've taken pretty much whomever he named first as a likely partner - the fact that he fake voted is definitely a mark against LL:
boat: LaLight
Obviously scummy scummy scummy for the information he provided.
After just a handful (3) posts back and forth with faust about the plan, Gkrieg then proclaims LL to be town, along with Joseph - who is town because Gkrieg wants to lynch him. This isn't anything really, but as Gkrieg had 6 total posts D1, it's notable as these remain the only two players he called out with any real reads:
BTW, this is town LaLight.
I also want to lynch Joseph real bad, so probably town there too.
Starting D2, Gkrieg opens by voting e for having quick-hammered PPS the day before. This is before e had claimed Cop, and while it could be Gkrieg trying to get on wagon early of a partner that he believes is going to pick up easy heat... it just doesn't feel like it - on the other hand, in the very next game post he votes for Dsell - so like D1, this could be a play at trying to hint to partners e/Dsell about his identity.
Next item of information is Gkrieg's claim: If Datswan is his partner, Gkrieg had the opportunity to fake claim first - but this is only true for Datswan, as they were the last two in line. If e or LaLight are Gkrieg's partner, then he already knew that mafia had fake claimed, thus making his claim of VT easy. He also knew that Datswan was likely a cop (having 1 fake claim and 1 real claim made thusfar), but he did not know if Datswan was the Insane or Sane cop at this time.
Gkrieg then spends most of the early-mid part of D2 trying to get Dsell/Me lynched for "coaching the traitor", which in the case is himself, and in this case literally nothing we said is applicable to the situation as the traitor wasn't a claimed cop. In post #462, he makes note that he thinks scum messed up by claiming the way they did because "they can't kill the cops because that will PoE them." - this seems especially applicable if one of e/LL is Mafia as their claiming prevented him from doing so in any way - if Datswan was his partner, he would've had control over the claiming as he would've gone before Swan.
In #525 Gkrieg says that e had the towniest cop claim, with LL being a very close second - this also does not lend support to Datswan being his partner.
#542 is pretty clearly telegraphing "Yo, scum buddies, I know what you did here because I'm the traitor" - but he didn't call out anyone by name.
In #594 he called out e's vote specifically on him with "This is a bad vote." - this does give marks towards e being his partner, and not LL/Datswan.
And that's pretty much all I'm seeing from Gkrieg.
Points for Scum!LL: 1st post call-out
Points for Scum!e: Much of his D2 seemed to center around finding e the towniest of the claims - but LL was close. The call-out on specifically e's vote on him being bad seemed partner-y.
Points for Scum!Swan: Really, there isn't much here. He didn't acknowledge Datswan at all D1, which could be a partner tell? And he found him by far the scummiest of the cop claims... but honestly, I just don't see a Gkrieg -> Datswan connection.
----------------------------------------
Honestly, I don't feel like doing a reread on LaLight. While I've personally found him to be the scummiest of the three cops by a fair bit thusfar - It's definitely just my gut feel towards him. I could put together a case, but it wouldn't be the best thing ever. He's posted a LOT, and rereading him and breaking down an actual case would take, like, real effort. So instead, I'll simply as that you indulge the theory below, let me know what ya'll think the likelihood of it being accurate is, and then we can proceed to lynch e, who is probably at worst, equally as likely to be scum as LL:
The theory is pretty straight forward: scum!LL + partner decided last night to double-frame the two town cops on the expectation that it was fairly likely one of town!e/town!Datswan decided to investigate a cop instead of their given VT targets. They knew there was Mafia in the cops, and that player couldn't give a false result in the way the Traitor could've - and the last thing scum wanted was to set up any potential for IC!Cops, as that simply reduced the lynch-pool today. In this theory, LL chose to claim a result on Mcmc, Datswan's designated target, on the idea that Datswan would've targeted either Mcmc (and thus would keep the potential for VT IC's to a minimum), or a Cop - which we've already covered would come back as a scum result.
