Ahh, The Bit Where Muir Reminds People Of Much Better Works.

It's the Day's Day of Days! Because The Black Widow.

This sort of underlines the problem with this storyline--the cast's incredible plot coupons aren't working thanks to author fiat, yes. But they shouldn't need them to begin with, as Trump has been portrayed as friendly to them, taking calls from and even calling them on occasion. The reason that's gone dark is the same reason Jo won't tell her what her powers revealed--they're both Muir's little power fantasy, and right now, that fantasy has been punctured. He thought he had a president who was his sort, and now he's vaguely realizing that he might not, and so Zed and Sam are suddenly written as being cut off from Trump instead of having a direct line to him.
