What is it with shoes? First Carl Grimes (Chandler Riggs) leaves a note about his lost shoe in The Walking Dead Season 4, Episode 9 and then a different lost shoe makes Beth Greene (Emily Kinney) cry on Episode 10.

Whose shoe was by the train tracks? Is there a mystery to be solved or is it just supposed to represent a child's shoe, so Beth may have assumed it was Mika's, Luke's, or Molly's but it was really the shoe of a completely different child? (Which is also sad, it's not like it's OK for kids we don't know to die.)

Yahoo talked to producer Gale Anne Hurd about the shoe Beth saw, noting that it looked like one of the shoes Mika was wearing. They also noted the Ep 10 structure got all Pulp Fiction with the timelines, so events aren’t necessarily happening in the order that we see them. For example, they showed Beth crying over that shoe by the bodies before the scene where Tyreese (Chad Coleman) came upon the group as they were attacked.

Yahoo asked Gale if it should worry us that a shoe that looked like Mika's was in a pile alongside dead bodies, or was it a coincidence. "As I said, there's always a reason behind our choices," Gale said. "We don't do anything particularly random." (She had previously answered a Lizzie-focused question with "There's always a reason behind the choices that we make showing some things.")

Mika still appears to be alive and wearing both shoes as she walks the train tracks to Terminus, so ... either Gale is going full Inception on us or those were not Mika's shoes.

TWD fans got curious about the shoes and on The Walking Dead Forums someone posted photos of Luke's, Molly's and Mika's shoes. Mika's are the closest-looking, but they also showed a screen shot of what looks like a little blonde boy being eaten by walkers (how pleasant!) when Ty first got to the tracks. It looks like it may have been his shoe. Beth wouldn't know that, though, since she just saw the pile of bodies when she and Daryl arrived a bit later. At least she was curious about Luke and Molly, who were all but forgotten otherwise! But maybe those two kids never even made it out of the prison?

Do you think Luke and Molly are still alive? Do you think there's more to the shoe situation or did it just function to represent Beth's loss of hope breaking point?
