I thought this. He can't remember where he got it, what it looked like, how much it cost etc. Then he just handed it over early one morning without any thought. No I think for someone in his position buying the ring would have taken thought and financial planning, and would likely have been something he thought alot about before doing. Im thinking he maybe didn't buy the ring at all but acquired it somewhere, and handed it over that morning because he knew RW was going to be in the company of someone that day who TM risked losing her to. That could be VB, could be someone else. Either way though it could, imo only, mean that TM knows who the girls were with that day, and where they where.
Teenage boy buying a ring, thoughtful enough to remember that Renee likes dolphins and getting ring with dolphins on it could require as little effort as:
- having few bucks (single digits) in pocket,
- walking into the store that has a lot of things girls like,
- asking to see some rings,
- being handed the selection of cheap rings,
- noticing that one has a dolphin on it,
- figuring out that's the one,
- buying it, putting it into the pocket,
- looking at it once again just before giving it to the girl,
- giving her the ring,
- considering the task is completed.
