Even with the sudden revelation that she was Melody Pond, River knew there was still plenty more to be discovered. She had plenty more secrets left, ones that she may or may not tell. Why she was feeling like talking about this, she couldn't say. Everything in her screamed to throw out her usual shield of "Spoilers" and wait for that television show to reveal them. After all, she knew the rules of time traveling, the effects it had on people. She knew better than to reveal things to the Doctor that he hadn't been through yet. But this wasn't their world. It seemed that the rules that bound them didn't apply here. So perhaps, just this once, she could break the rules, warn the Doctor about what he would face very soon if they ever got back to their world.
Thinking about it now, perhaps his act of saving her in the Library was repayment for saving him, for what she'd sacrificed to ensure his life. It broke her heart to think of that time, back in 1938 Berlin. But the truth was, she'd do it all again. The only thing she would change was the brain-washing. Going back even further, she wished the Doctor had kept her from being kidnapped at Demon's Run. That's where everything began. If he had saved her, then perhaps she never would have tried to assassinate him. She'd still have the ability to regenerate. But likewise, she'd undoubtedly be a completely different person. And, frankly, she liked herself the way she was. Well, mostly. There were a few things she could live without, but that was beside the point.
River knew the Doctor hated that he couldn't figure her out, and she did like teasing him about it every so often. She did have to wonder if knowing she was Amy and Rory's daughter would make him more or less curious. Then there was also the issue of him trusting her. Would he trust her now? He certainly hadn't when they'd been dealing with the Silence, or really at any point before that, in his time stream. But knowing this, would she finally look at him and see recognition in his eyes? She missed that look, him knowing who she was. Would she finally be able to have that Doctor back? She couldn't help but feel a twinge of excitement at that thought. It had killed her every time she looked in his eyes and saw nothing but confusion and suspicion. Would that change now? And what about his Tenth regeneration? Would he, too, have meaning in his looks? Or would he still be completely clueless? River didn't know, and to be honest, she had avoided the Tenth Doctor simply for that reason. She had just been in the Library, she didn't need to deal with that pain again.
Just as she'd thought, the Doctor had been tinkering with the TARDIS. He always did that, always trying to improve it or fix it. She briefly wondered what he'd been trying to do this time, knowing he must be going crazy from not being able to travel. She was getting restless herself, but her trip around America had helped settle her a bit. Next time she'd perhaps go to Africa or Asia. She hadn't decided yet.
When he gave her that grin, she couldn't help but smile in return. Oh he could be such a child sometimes! But that grin was infectious, as was his enthusiasm. When he wasn't getting under skin, that is. No one could grate her like the Doctor could, but likewise no one could make her laugh like the him.
"You fancy American cuisine, then? I could've brought you a nice big hamburger to go with the fries." She chuckled, handing over the container of fries. A few were missing, as she'd munched on her walk there. And she felt relief, again, at hearing that her being a Pond was good. "I'm glad you think so. It is very good to be a Pond." She wasn't exactly sure how to even start this conversation. Though she figured she should start with explaining Demon's Run as that's where it all began. "A Pond that's part Time Lord, which could be a scary thought if you think about it." She couldn't help a little smirk at that.
