Mark tensed when Len stopped. He saw it, too. Either Lisa was back, or something and someone had done one hell of a good job finding a doppelganger. He stood his ground as Len yelled at the patrons, staring down anyone that started to question. He gave a reassuring nod to Jan, adding a more than proper amount to her tip jar. He followed her trail to the backdoor and locked it, then passed the two (maybe) Snarts to lock up the front. He knew at this point, any interruptions would be met with a scowl and probably a cold gun. He leaned up against the wall opposite of them, giving Lisa another look over.
