"Oh." - such a small, yet meaningful moment of clarity in the kitchen scene of the Walking Dead's episode "Alone."
Beth asks Daryl what changed his mind about good people still remaining in this world, and though at first he seems reluctant to give a definitive answer, Beth is relentless. When she asks him again, "What changed your mind?" Daryl pauses, seems even uncertain at first, then his gaze focuses on her.
And there is silence.
So much is being conveyed with his expression and non-answer alone, words seem almost intrusive. It's only when the moment seems to weigh heavily in the air, do we see Beth realize...something.
Because what else could she say?
