It looks like he prints off two tickets, yet the boarding pass says Lester each time he prints. But then he's clearly holding two pieces of paper when he tells his wife he's got the tickets.

Storywise, it doesn't make sense to me why he would only print one. He's got a paranoid suspicion that Malvo will come for him, yet he's hoping that he can get the passports and fly out of there before Malvo arrives. So if his wife was able to get the passports, how would Lester explain only having one ticket? I think he printed two.

Also, after rewatching, it's pretty clear that Malvo confirmed the kill and realized it wasn't Lester. I thought Lester's orange jacket plan was underestimating Malvo's assassin skills, and the sacrifice was unnecessary. Malvo is still gunning for him an hopefully Lester will get his next episode.
