Shanks and Teach can’t have the Last Road Poneglyphe, because if Teach did he would have all 4 now after beating Law, and if Shanks did he would ether have all 4 or he would just need Zou’s. Shanks only needing Zou’s would make it too easy for Shanks as no one on Zou could stop him.
If one of the islands in Road to Laughtale does have the Poneglyphe and we eliminate all the ones explored by Shanks, Big Mom, Luffy, Kaidou, and Teach, and eliminate the ones already passed by the Straw-Hats as I don’t believe they will back track, this only leave Emptee Bluffs and Vira.
Vira being one of the Top 3 locations mentioned gives it the nod in likelihood though.
