Hey Nav, pretending to be a dentist would require the right situation, proper equipment, training, skill and confidence.
Malvo always seemed to have enough background, expertise and things he needed to succeed at whatever cover he chose.
I imagine there have been and are unlicensed dentists (and fake clergymen) practicing illegally, if you'd investigate enough.
Especially if he'd join an existing practice or church as an associate or a part timer or as a substitute.
It would take chutzpah and Malvo had plenty of that.

I enjoyed the show.
Watched each episode twice.
I never thought Lorne Malvo was supernatural.
When he was pictured standing on up on the roof of that supermarket after the crickets were released, in plain view for anyone to see him, that was the main WTF moment about him for me.
I guess that's where he put the crickets in the air conditioning.
Nevertheless....
I mean, he was always hiding in plain sight but being up there on the roof like Moses looking down from Mt. Sinai or some evil overlord from The Lord of the Rings, surveying his latest accomplishment, was a little hard for me to accept.

I hope Molly and her family and some of the others are there next season, if only at the first as continuity to introduce a new story.
However, I trust these producers and screenwriters will doubtless come up with things that will interest me.
More sexy stuff would be good too.
