What is the significance of the ring?
Much has been written and speculated about Teresa’s ring. While it seemsto have a sort of teleportational power for Agent Desmond and perhapsLaura (in the train car), we do not know why it did not have similarpower for Teresa Banks. Because it appears in Laura’s dream, held by theMFAP and warned against by Cooper (and possibly for real in her hand) andon the hand of the one-armed man, we know it is somehow connected to theLodges. Interestingly, Teresa’s ring in FWWM is not seen in the series. WhileCooper temporarily loses *a* ring to the Giant, it is not the one we seein FWWM with the owl cave symbol on it. We don’t know if it was meant tobe the same ring, though. A ring also figures into Cooper’s autobiography. This continues to be one of the most discussed topics in the alt.tv.t-pnewsgroup.
