I am going to make them longer I swear...the next chapter will be longer and everything amazing and beautiful will be happening in that chapter I promise.
Tony knew that what he was doing was dangerous and could blow up in his face, possibly hurting someone. He understood why Bruce was afraid but he just wanted the man to see how god damn wonderful he was, instead of always seeing himself as a monster. He wanted to show Bruce how truly amazing, he wanted to help him get past his fears, to accept that he really was a good...no a wonderful person. So kind and caring, with a wicked sense of humor that was rarely shown. He wanted the man to trust himself. This was Bruce's biggest issue, trust...not just with others but more with himself. Even before the incident he had had the problem of trusting himself near others, letting them see him for who he truly was and after the incident...well he got worse. Bruce believed that every accident and mishap the Hulk had was his fault, that all it took was something simple and he would lose control.
It wasn't his heart rate that made the Hulk come out to play, it was the fear that came whenever he got into a situation where his heart rate jump. It wasn't fear from the event or situation but a fear of the Hulk itself and naturally the big guy reacted to it. Tony watched Bruce enough to notice this. If Bruce didn't worry so much over losing control it was less likely to happen. Having his heart rate increase didn't have to be considered a bad thing and Tony wanted to show him that. Like when they kissed, Bruce relaxed before his brain could precess what was happening, giving him less time to freak out. If Tony did it smoothly and fast enough, Bruce would give in to the kiss, and wouldn't freak out. He wanted more than just the soft stolen kisses, he wanted to give Bruce more, to prove how much he cared about him. It was more than just physical attraction to Tony, he loved every little thing about Bruce. From the clever quips that he normally kept to himself to the way he would watch Tony out of the corner of his eye when he didn't think he was paying attention. He was gorgeous, even if he didn't see it, Tony did. He was lean but strong...even with the Hulk, Tony was sure in a bout of wrestling he would be able to hold his own quite well. He had those sweet, gorgeous brown eyes that dragged you in when he was talking. Seeing him without his glasses was breath-taking but he was just as attractive with them as he was without them. Tony was addicted to looking into his eyes, running his fingers through his soft hair whenever he could, feeling those lips against his own, startling him on occasion just to earn the small sound he earned in return. Holding hands with him was wonderful, their hands fit together like a two puzzle pieces and it made him earn to contemplate whether the rest of them would fit together so perfectly. But most of all he adored his brilliant mind and the thoughts he held within it. Tony liked being with people that he could hold a conversation with that he enjoyed and being able to sit in silence with no need of words. Both he could have with Bruce.
The Hulk is included in all of this as well. Just another part of Bruce, another part that Tony adored. A part that was misunderstood by everyone including Bruce. Tony paid more attention to things than people gave him credit for, the Hulk wasn't a monster. He was the part of Bruce that he kept hidden, all his emotions that he kept locked up the Hulk expressed. Anger mostly but fear, sadness, regret. He felt all those and instead of hiding them, he turned them into anger. The part of Bruce that Bruce hated the most was his anger because it hurt people but Tony had noticed that when Bruce let his emotions out, you could see the other side of the Hulk, especially when he willingly gave control over. There was the glint in his eyes, something that showed relief and a bit of calmness. The Hulk also considered himself Bruce's protector which was why when something upset Bruce he came out. It was a bad thing, just something that was reflexive. Something that needed to be understood, the Hulk is ridiculously smart, not unlike Banner, he has a mostly quiet nature. He achieves more through his actions than his words where Bruce is the opposite, achieving more through words than action. Tony and the Hulk got along on missions, the Hulk listened better to him than the others, and Tony gave him more respect, just as he gave Bruce more respect. The Hulk had saved his life, he owed him. The big guy didn't seem to understand Tony's need to pay him back for that, so Tony had decided to pay his debt to Bruce instead and this was how he wanted to do so. He wanted to make the man see how important he was, to see that he nor Hulk were monsters, that they both helped and functioned in their own way, that in the end Tony loved both of them and that wasn't going to change. The Hulk wouldn't hurt him, and that was what Bruce was the most worried about. This was what Tony had to show him before it could go anywhere else.
