I can see a town player making this play but it absolutely doesn't confirm her action, and unfortunately her N2 and N3 actions aren't confirmed either. MS still 'feels' more like the merger to me to the point where I still feel like lynching them in spite of this, but I thought this information was worth sharing.
So, N3 Lenglon claims to have not been roleblocked, but to have gained 'Marked By Death'.
That was core of the case on eliminating
BlackHeartKabal was executed. BlackHeartKabal was Mafia.
Ghost Racer (Mafia)
(Auto) A Lonely Road: What accompanies you cannot be seen. If you are visited during the Night by a living player, any Night actions you attempt fail, and the visiting player gains Marked By Death. You will learn that this Auto was the cause of this failure.
(Night) Deadlands Drifting [target]: You crash into your target’s soul and jostle it, issuing a challenge. They are roleblocked, and gain Marked By Death.
(1-Shot, Mafiakill, Night) Final Circuit []: You begin the Final Circuit, inviting every player Marked By Death to join you. You kill every player that has Marked By Death, bypassing protection and kill immunity. Then, you claim your prize - at the end of the next Day, you may replace A Lonely Road with a copy of one non-Innate Auto ability that one of the players you killed had.
The main issue was they had claimed roleblocker who gives that mark, then claimed they visited Esteemed Lenglon to only give mark.
But Lenglon claimed inspection results of both 'has a group chat' and 'doesn't have a group chat' despite claiming single use of ability.
It appears that Esteemed BlackHeartKabal did get visited by Esteemed Lenglon, and was roleblocked by the visit, and got inspected as having a group chat, and thought 'I muddy this water, or I'm dead' so lied about being a visitor that just didn't roleblock.
Esteemed Maximum Spin, who seems to know who is town, and may also know who is scum, seemed unerringly focused on the lie between these two, and we settled on Esteemed BlackHeartKabal to eliminate, good call.
Esteemed Maximum Spin is clearly concerned about Esteemed Lenglon, which is interesting in its own regard.
But, in terms of 'who is the merger' - it seems certain that Esteemed Lenglon visited Esteemed BlackHeartKabal N3, gaining the Mark, which might interfere with also being the merger'.
