I'm pretty sure UwU is scum - the protect doesn't mean a great deal without knowing the particulars of what it entails, could offer some form of control over the role.
For orange I would probably say Ekko. Juliet protecting Ekko was entirely self-serving, but between that and it being hime all along I would say it's more plausible that it was to protect a scum mate. Really if Ekko was dying, Juliet would have to use it anyway.
It's not going to be Charlie. He doesn't have the kind of woe is me petulance fakeable in his wheelhouse. So for me it's between hime and Ekko. I would lean Ekko there.
I would like to say I'm confirmed town because I don't fit on any team, but something tells me that won't be the sentiment I receive.
Not really sure what else to add here - I feel like of the teams could merge they would have done so, but we should consider this the last phase the Town has to clinch the win.
