Tobias always tugged at my heartstrings with just how bad he always has it, but I've never actually developed a crush on him. He's a little too down-on-himself too often for me to develop any romantic attachment. I'd have to go with Jake, he is way too underrated. For someone who carried as much weight as he did, he held up surprisingly well. He's not the funniest, and he's not the dreamiest. But I loved his silent contemplation, and even if it was never explored nor was it ever as compelling as Rachel-Tobias, I always loved his scenes with Cassie. As awesome as Marco would be to date it would burn out eventually. With Jake there's this assured stability, and realistically he would be the only male character in the entire series I could see myself staying together with long-term.
