She means she likes your second idea.
As a tip, it's really a good idea to do some brainstorming yourself, Silver. The reason why is because it's your second chapter. If you're encountering some serious writer's block now, you'll probably find yourself in a difficult position come chapter six or more. I say this because the deeper you go into the story, the more you'll need to rely on yourself to produce ideas because not everyone will be caught up to give you advice. Moreover, the plot should be moving faster by then, which means everything you do needs to be with your plot in mind. (That just means asking us for help would require spoiling your story because we won't be able to give you feedback without knowing what you're planning on doing later. It's all pretty much part of the philosophy that everything that happens in a story happens for a reason, basically.)
That all said, there's a few ways to come up with ideas. For example:
1. Take a blank sheet of paper and write down the first concepts that come to mind. Keep going until your head accidentally puts together words that you like and use that. Sometimes, stream-of-consciousness writing produces the best stuff.
2. Take a break. No one says you
have to finish the next chapter within a couple of days of the last one. Save your work in a word processor (like
Google Docs and come back to it later. This tip I recommend highly because you're trying to write something at midnight. If you have to emphasize those words, I'm guessing you're not used to being up that late, so you're probably tired. (I say "I'm guessing" because there's some people out there who do their best writing at two in the morning. Yours truly, for example.) Save your work and go to sleep. You'll be able to think more clearly after you've had some rest.
3. In the same line, save your work, get up from the computer, and do something else. Listen to music. Watch a movie. Take a walk. Giving your brain a rest from your story will help you approach it with a clear mind later. You'll be able to read over what you wrote as if you're a reader instead of the frustrated writer, so you'll be able to approach the chapter and get an idea of where it
should go. And I know this doesn't entirely make sense, but it's hard to explain. You'll know what I mean if you try it, pretty much.
4. Think about what you
want to do. Writers very rarely start stories when they don't know what the general concept will be. For example, you probably didn't write the first chapter without knowing what the overall story is, even on a bare-bones level. Judging by your first post, you've already got a built-in example. Your concept is that Vanilluxe is rescuing Gothitelle from a dragon-infested castle. Now that you pretty much have the ending (Vanilluxe rescues Gothitelle), work backwards. Who put Gothitelle in that castle? Why? Was she always there? If she was, how did Vanilluxe know about her being there? And so on and so forth until you get all the way back to your first chapter.
I hope this all helps a little, but my main point is don't ask for ideas. Not until you've exhausted yourself going through the above four points (and probably more that I'm not thinking of). Eventually, you'll reach a point where we can't really help you, and really, no one knows how a story should go better than the author (which means, technically, we shouldn't be giving you ideas right now anyway because every little thing can feed into what you were thinking of doing way down the line). It's really best to ask us how to get around writer's block and maybe what we think of certain ideas you have in mind while just doing some brainstorming exercises on your own, at the risk of being blunt.
