Why Doctor Strange Gets A Third Eye At The End Of Multiverse Of Madness
The Third Eye is essentially Agamotto's Eye, a talisman that is designed to reveal the truth to whoever wields it. The Eye of Agamotto is given upon someone with good intentions and a decent heart in the comics. doctor Strange's intentions were good, since he only used the Darkhold to prevent Wanda from snatching America's talents, which explains why he holds the Third Eye. It's likely that he'll utilise it again in the future.
The fate of the doctor Strange is obvious as we saw the end credits rolling with the line doctor Strange will Return but not Wanda Maximoff or Scarlet Witch
