What he said didn’t make a whole lot of sense for that, though, unless he was just putting on a show in case someone overheard. (Which Mustard did) He did say where they’d be and when, but he seemed to be genuinely not sure whether to expect anything. Still, he or Oats seem like the most likely candidates at the moment. Mustard doesn’t seem the type, and also it feels like her antics with McBell were probably part of what was meant by things not going completely according to plan.
