I'm not so much saying there's no scum on the Evan wagon, but more dissagreeing with people saying there needs to be a great amount of scum (3+) on the wagon. If Randa was town, scum had no reason to try hard and get Evan lynched either. It's also possible scum was fully intend to bus Randa and didn't find a good reasoning to switch and/or hard push Evan. Heck, maybe they were on Evan and were planning to push him like mad to save Randa, but enough town went to him on their own they didn't need
