It will go something like this: Morgana will gloat and Gwen will be quietly noble - then state that she can’t believe what Morgana has become, what she let Morgause and magic do. That’ll be where Morgana will state all the ways Morgause and magic saved her, gave her strength … Gwen will then ask what about her (their friendship)? Morgana will then point out that their friendship wasn’t enough for Gwen to notice how she was suffering. THEN Gwen will quietly remind Morgana that she had been devoted to being there (and suffering with her forever) - to which Morgana will feel a prick of guilt. However, Morgana will rally back with the Arthur argument (because everyone picks Arthur). Gwen will feel guilty. They will both ponder and miss each other and NOT forgive each other but realize they did the other wrong. And come out stronger women for it.
…. or Morgana can just throw Gwen up against a tree. Whichever.
