Clarke didn't know much about the poppy situation, except that she needed to avoid them. She had heard about some of the effects it was having on people. And she was certain she didn't want to fall asleep, go psycho with violence, marry anyone, or be forced to tell the truth. And now it seemed there was one more they could add to the list. Some poppies made you drunk.
When Finn had posted, Clarke had been cetain he had to have been drunk. Nothing he was typing made much sense. It actually took him a few tries before Clarke was able to even decipher what he was trying to say. She was immediately concerned, because while being drunk on its own wasn't necessarily bad, being drunk in a place that was as dangerous as Las Vegas was, could be.
Finn didn't seem nearly as concerned as he should have been. Another result of the drunken poppies, she supposed. And if he couldn't get himself away from there, she was going to have to go and get him, herself. She'd be careful not to go inside. Oh, she really hoped he wasn't inside. Because drunk Clarke and drunk Finn likely would not be a good combination.
She was relieved when she saw him outside of the place. That was better. If she could just get him away entirely, that would be for the best. As it was, with every other poppy, the effects didn't wear off right away.
She was nervous that he was going to fall and hurt himself, so she made her way over to him quickly. "Finn, how about you step down from there and we get away from the palace? I think we're forbidden to be here." A childish lie, but she had to do something.
