Logistics and logic I understand using public transport. I understand wearing masks. At what point do you make the transition between the two? If you leave home as Guy Fawkes, you're a giveaway. If you put it on on the train, you're a giveaway. If you go into the station loo when you get to your target and come back out as GF, you're a giveaway. If you put it on outside the CoS building, you've failed miserably. And then in reverse, at what point is it safe to remove the mask? Scilon follows you onto the train, you've got a major problem surely?
