Silly writer, ripples are for kids.
Move on. Worry about tying it together later. Worry about whether one scene/character/event contradicts another one L-A-T-E-R.
Write now - revise later.
Do I never want to finish this little thing? It's my first book- let go of perfection in first draft. Trust the process. Trust the subconscious to handle the details (or cut and change stuff later). I PROMISE to have a "Lost Scenes" section on my author website. No effort is wasted and why take all the fun out of the first draft? All this worry has dragged down my writing and blocked me up.
Breathe deep, let it go, trust the process. Move on and dive deep.
