Maybe i'll remember other things too but this 4 are the Top unrealistic things in my opinion.

This was so annoying and completely ridiculous. And also the Echo one, kinda. The other two don't bother me.

I haven’t seen season 4 so I can’t say about the last two, but I agree with this one. I like the idea of Octavia becoming a badass warrior and all, but it happened too fast. The Clarke/Lexa thing never stuck me as unrealistic, yeah the Finn thing was messed up but Clarke understood (even in the moment, I think) why she did it. Also, love is weird & doesn’t always follow the rules of who you should fall in love with and who you shouldn’t, in reality as well as fiction. Clarke knew she shouldn’t love Lexa, but she did anyway, which, to me, seemed perfectly realistic.

All of these, but ESPECIALLY this one. I mean, wtf? It honestly gave me whiplash. One second she's a good person who preaches peace and backed that up in her actions by leaving the nightbloods, and the next second she's just a psycho murderer who wants revenge and the human race to die off? That's not how it works. It's the same shit they pulled with Finn murdering innocent people, and it's just as flimsy/rage-inducing.

Luna was the biggest switch, I didn't understand it at all.
The Clarke/Lexa one, too. I could've liked Clexa if Lexa hadn't betrayed Clarke at the Mountain.
The Echo one bugs me too.

But okay. The Octavia one. Yes, it was quick, but we don't see how much time she spends training to fight. We can imagine that we had training, because honestly, she's amazing. But we don't see Lincoln, Indra, and whoever else train her. So *shrug* I guess it's all about how you interpret that.
