Radcliff's ending: INCREDIBLY satisfying. That was a great way to handle him. I kind of thought there might be another way out for him, another real-world human body printed or something. But... this was a good way for the character to go out, finally out of room to wiggle. Very dramatic, final, and poignant.
Whole episode has been fantastic (and as I type, not over), but that was very well done.
