This is your typical "I have the opportunity to kill the bad guy, but I'm not going to (for the sake of fake drama), so that the bad guy can come back literally 2minutes later and find me".
This is extremely unrealistic, as no logical, normal character would leave their archenemy alive... it's literally like you have the opportunity to kill Hitler, but you don't and you just run away... nobody would do that, and yet, in this episode, that is exactly what the writers wrote. It just completely breaks the immersion of the story, and makes you realize that you're just watching some scenario with some actors, and that's it.
