Supernatural was on Wednesday and I'm still not ok

Oh?

it was as the fandom would say very much like Romeo and Juliet. Sam was shot and Dean took lot of pills when he thought Sam was dead

Oh. Okies.

at least Sam and Dean both lived unlike the famous tragic love story

That's good.

But there is always the danger of brain damage

True. But this series isn't going to damage their main characters.

We don't know that

Unless someone is quitting most series don't kill off or damage their main characters. They'll end up with a lot of angry fans.
