Cal.
He notices the smallest things, the micro-expressions...because that is his job. But yet, he is also blindly unaware of the really big things, the things that really matter.
How, after 8 years, is he still oblivious to her? Yes, he notices her amazing abilities, her figure and of course her love for chocolate pudding at 10 in the morning. But how, how could he still be unaware of the way he clearly feels about her? How everyone knows they feel about each other? But he appears to not know the way he feels himself? Is it possible to love someone for eight years and not know you've been head over heels for that entire amount of time? Is it possible that after a long and emotionally straining case, they both want to be around each other for comfort, but yet he still doesn't know that he NEEDS her? That Cal needs her smiles and her ability to make his shit days bearable? That not only he needs her, but she needs him? He says that the Lightman group wouldn't be around without her, but in truth it wouldn't be around without the TWO of them; without their teamwork, their history, their passion, and clearly…their LOVE and complete RESPECT for one another.
