Noticed during testing with friends while waiting for match.
If Doorman uses his Ult at the same time Paradox uses her Ult, 2 version of paradox will be created - one where the Doorman Ult was used (with the Key stuck in her) and the other will swap with Doorman. Then when the Doorman Ult expires, paradox will take full damage (as if she didn't escape the Baroness) and be teleported back to where the Ult was used.
