Taylor Trensch pops up in Act 2 as an aptly super-bratty Mordred but “Fie on Goodness,” the turgid song with which he stirs up the aggrieved roundtable knights, deserves its own “fie!”

Following an epic battle, Merlin banishes Morgana, and her son, Mordred, to the ends of the universe.

As Mordred, Arthur’s dastardly son by another woman, Patrick Vaill enlivens the proceedings with a bracingly sneering dynamism.

White’s “The Once and Future King”: “Mordred and Agravaine thought Arthur hypocritical, as all decent men must be if you assume that decency cannot exist.”

But in Andre, “Empire” has something truly formidable: a wolf in Lyon’s clothing, a bipolar Mordred to Lucious’s twisted King Arthur.
