That walker was shown at the beginning in the morning, and at the end of the episode during sundown. Both times, Shane stares at the walker in the field.
I think it represents Shane's state of mind. Nothing has changed in him, he still loves Lori and Carl and think they are his own, even though he seems to accepts Rick's terms.
