Oh don’t worry, I fully intend to create a cut that resolves all the plot lines for everyone, and will be waiting for episode six, I just thought it’d be a fun experiment to try and end it with just what’s presently available since it gives you so many avenues for that, at least for Sam.
As for Bucky, I’ve found it less time consuming not to focus too much on Yori. I still have him being referenced as a name on the list, but I haven’t used any of his and Bucky’s scenes so far. When I get the sixth episode, and if he’s included, I might include the stuff I missed out on episode one to maybe extend their scenes together if they’re short. Though, as you say, I’m being very speculative.
I think I can squeeze just about all of episode six into the run time, so it’ll come out at close to a three-hour cut.
