The mandate in modern “bad television” (by which I mean anything following the CW formula) is that literally every character should be secretly terrible. There should be one (1) betrayal every episode, treating a straightforward story like a Twlight Zone episode, with a big twist at the end. Did everyone come up with a plan in the second act? Well, just before the commercial break expect a previously good character to sneak off and pocket/unpocket some mcguffin denoting that they are going to betray the plan. They will do this because they want to “save the person closest to me” at everyone else’s expense. The end of every episode will have a dramatic reveal that some person is “not who you thought they were”, and that exact same person will have about 5 or 6 of those by season’s end. Is the overall story ostensibly about how good conquers all? Be assured that being good will get everyone into an impossible situation, and only by compromising their own moral code will they get out of it. Then, after the problem is dealt with, they will rend their clothes and gnash their teeth about how they will “do better next time”. (They won’t. When push comes to shove, the good characters will always be forced to compromise their beliefs by the end of every season.)
This is modern “teen drama” television. Enjoy.
