Q: Who is (insert character here)?
A: Questions about characters always come up, here are a few:
Who is the guy behind the tree when Leo, Bobby and Mike meet?
We really don't know. It's rumored to be either a) one of Leo's buddies, or b) Leland.
Who is the guy who beats up Jacoby in the park?
It's Leland because later in the series, Jacoby mentions that he smelled scorch engine oil. Due to the clothes that the man is wearing, some have connected him to the guy behind the tree (previously mentioned).
Who is that strange woman with the bag over her eye at Fat Trout Trailer Park (aka Curious Woman) and who was she played by?
She was played by Ingrid Brucato, and no one really knows who she is. Some have suggested that she is Carl's (Harry Dean Stanton) wife and others just say she lives in the trailer park. Mike Dunn did an interview with her and can be found here at Lynchnet.
Who is Judy?
In 2003, Wrapped in Plastic interviewed Robert Engels who said that Judy was Josie's sister. If you don't like that idea, then others believe she is an integral part in the Black Lodge/White Lodge makeup.
