So, here's something I just realized. We know that Ekko and Heimerdinger were sent to an alternate reality. However, based on what was shown with Ekko, we that they didn't just get sent there, their consciousness took over the bodies of their counterparts.
With Ekko, when he returned to his own reality, his consciousness left the mind of his counterpart. But what of Heimerdinger? Either he died or was zapped to yet another alternate reality. So what happens with the Heimerdinger of the alternate reality? Did he die? Is he still being controlled by OG Heimerdinger? Did their minds merge? Lots of questions.
Thoughts?
