Hey Alex, sorry it took me so long to read your post.
As for which scene would make a better opening for chapter three, perhaps the one you put on top. However, all the pieces that you posted can be worked into your story somewhere.
You will have to get around to telling us what happened at the end of chapter two at some point though; you can’t just leave us hanging on that forever. Okay, so you can, but you better not.
As always, I keep waiting for the rest of the story.
