A Thinning Border-Line

I have taken notice of poetic justice or irony in the episode Two of The Twilight Zone. After the woman in the show betrayed the guy's friendship and ceasefire silent truce, she got exactly what she wanted: She got loneliness. Her melancholy and repent are reflected on her body language: When she is in the dilapidated edifice, her jumpy mood shows how she is repented (probably because the fact that she is pondering her choices and is in an internal conflict between her duty and her emotions make her separated from her surroundings). She hugs herself while attempting to fall asleep, all the while holding on to her rifle with a grasp as for the safety and assurance she would have had would she have been allied to the man. She feels unprotected, stupid, and confused, trying to cope with the fact that she chose her long-achieved duty over freedom. Poetic justice in this case would also involve her hypothetical alienation by anyone she meets, what happened to the man.

The following comic strips depict Garfield involved in an event that implies poetic justice.

The first describes poetic justice, while the second shows irony, I believe. The line that separates irony with poetic justice and Karma is thin.
