In Episode 9, Linda tells Karen it's her turn to do the roadblock, because she did it last time. Huh?
Going back to Cali's recap for ep. 7, we see it's Karen who did the roadblock, so by that logic it's Linda's turn now. Obviously, there was no roadblock in Episode 8, thanks to Colin's tantrums, but this is a bit of editing that has bypassed CBS who are trying to pretend that there never was a roadblock, when that remark clearly shows there was.
It might not have been the most interesting of roadblocks, but I'm a completist and hate missing out on things. Maybe in an interview john could ask the moms what did happen in the missing roadblock?
