Lex smiled blissfully and approached Lisa. With her being there for him, he felt like he was the luckiest person in the world. She was finally his, just that fact sent butterflies in his stomach.
There were many people who supported him later on, like Grandpa Max, Denver and many more. However, they came later when he had almost brought his life back on track. They weren't there when he was suffering in the outskirts with Elise.
It wasn't their fault and he didn't really blamed them. In fact, he was very grateful for everything they had done. They provided him with selfless love, what more could he want from them. Whatever he needed, he was given while they demanded nothing in retur. Well, aside from one thing. They had asked him to be happy and smile more.
