Yowsers! I sewed right through my finger at the edge so I didn't catch the nail; I did that about 45 years ago with my mom's textured black Singer 66. It did not catch the bobbin thread - LOL. I remember that surprised me since that Singer sewed through everything! The needle did not break. It happened so fast that it was over before my brain knew what happened. I do remember it was mighty sore for a while. I sure would hate to think that there was a piece of needle left in there. Can you compare the two pieces you have to a new needle and ensure all is okay? Let us know how this turns out.
