I really liked this week's episode, best of 5B so far imo.
Spoiler:
I actually found myself feeling bad for Milah when Rumple threw her into the river, never thought I'd be feeling sympathy for her. I internally cheered when he killed her back in Season 2.
Speaking of, I really liked the River of Lost Souls and how reminiscent of the river in the Hercules movie it was. It really took me back to those scenes that always creeped me out as a kid when Hercules descends into the river and starts rapidly aging.
