I hope Calus comes back honestly
Bit of a take but I really do he comes back in one form or another, however, I was watching and listening to the dialogue of Menagerie and man does it ever hit different ya know? Just being this third party entity, really taking a shine to the Guardian, would love to see that side again, taking the Darkness with him but being this entertaining dude at the same time, hopefully saying something along the lines "Oh is it ever MY ambivalent Guardian, oh I know how we have fought, it has given me a new perspective, come, let me shower you in riches, let US take the powers of the Witness and Traveler for ourselves, would it not just be the grandest of treasures to share?"
I just miss him giving all of the lavishing compliments
