Very good with the parallel observations, I completely agree. Some obvious parallels there. Maybe a bit too obvious for some, but others may not notice it, so I don't know whether to conclude it's clever writing or not. Considering this episode pretty much regurgitated already exhausted arcs, I'm not exactly going to call the writers clever.

Check out this review here, I think it hits the nail on the tip.
