You're making cogent arguments, but alot of times, cogent arguments aren't enough to convince people to make the right choices, and this case, they're writing Lana as being hurt and betrayed and her feeling she can't trust the Kents. I don't like that they're putting her in that position, but I'm not writing the show. I'm not saying it's a good decision , to be clear, because , I don't. I clearly didn't like how she behaved in the episode, and I don't think her decision was correct . But, I'm saying I can understand why she could jump to that conclusion, even though I don't think it's a sound one. You can understand why someone makes a decision while at the same time knowing its a bad one.
