Uh…Starlight?

As starlight glimmer was pulling trixie’s wagon when at the peak of a mountain had starlight glimmer think the wagon was much lighter when something happened to the harness when the wagon was starting to roll backwards with trixie still inside. With the time trixie traded her wagon on a class A diesel pusher could have times in winter when warnings for freezing rain had times she believes the tires lost traction when she spun out and was rolling backwards.

I’m not entirely sure that’s how Trixie rolls.

I think you snapped the pull rope

In background where Trixie is:

One my favorites, actually.

and of course when comes to a complete stop it is exactly where Starlight is

Seen this happen before.
