While changing the radio out on my girlfriends 2004 civic(hybrid) I managed to drop a socket somewhere behind/in front of the cup holder . I put everything back together, drove it and everything seems to be fine. I really don't want to take out the entire center console if everything will be fine for a little socket. I was just wondering if there is risk of something happening that can screw something up later on down the road? Also what exactly is beneath there?

Any help is appreciated guys.
