I was told Ekko was the one who destroyed one of my shots. He probably has investigation immunity but this ability that informs me doesn't actually target anyone, hence why I received results (is my guess). I think Ekko's reaction to discredit me but not push me, and then with no follow up suggest I should be one of the top two wagons, indicates that he's scum and feels confident I was reaction testing but not confident enough to actively push me. Odd has good chances of being his scum buddy. If Ekko were town, he'd know he destroyed one of my shots so he'd know I wasn't reaction testing, and if he didn't, he'd be coming at me big time for lying. It's not a 100% surefire lynch, but it's good enough.
