Thanks, Candice! Sorry I wasn't here earlier.
Most of the points you mention were details I noticed, too, as seemingly minor things I had forgotten but now recognize as possible foreshadowing.
I was a little surprised at the seeming disconnect from these earliest episodes to the later ones, especially regarding Big Jim.
There are things you only notice when you have the whole season to look back on.
BJ was a Bad Man from the beginning, but very cunning - and never more so than in Manhunt; by the end of the season, he was completely irrational.
I hope the writers have a better season-long plan for S2.
