I think you've gotten everything that you're going to get from Shos on this. I hope you don't mind me interjecting here.
I don't feel those quotes disprove a Syryana - Parama connection. You're overlooking the possible motive of Syryana distancing himself from Parama because of the hammer. I would weight that type of quote more heavily in favor of there not being a connection, if that sort of interaction had happened before Parama's hammer.
As there may be two separate scum teams, I do not understand the push to try and make Shos tie all his suspects together as one scum team. As Shos himself did not try and tie Syryana and Parama together, why make a big deal about these two scum suspects not fitting together?
Somewhat related to the above, Shos case on BBmolla is too weak for me, currently. Sho's case on BBmolla is based on Parama defending BBmolla. If we assume Parama is scum, then we are left with the question of whether his behavior towards BBmolla is the result of buddying up to a townie or actually defending a scum buddy. However, if we assume that Parama is town then we are left with no actual case on BBmolla. I won't support this argument unless Parama flips scum.
