Personally, the Clark-Lex bromance in seasons 1-4 has been one of my favorite things about Smallville. I loved seeing them as friends, but despite how heartbreaking it was I also loved the way their relationship developed to finally become what it was destined to be.
There are many people I've seen on other platforms-especially YouTube- that see Clark and Lex as a romantic couple. I think they most certainly never were and never could be. I'm not saying this because I am homophobic or something but all I saw in those two were (in the first few seasons) guys trying to become closer friends but just couldn't stop lying to each other for their respective reasons.
And since Lex is my favorite and Clark number 2, I just can't help but see this as an amazingly well done relationship.
What do you think?
