Yeah it feels forced, like an idea that author wanted to convey about Nobunaga's distrust and inner conflict but couldn't fit it in.The chained up in a basement and strangle thing felt like it didn't have to happen. I'd rather see them talk it out in that japanese style room and solve it that way. Now it just feels like it was extra drama added to the end and then "oh yay happy ending" Maybe that's just me.. But at least it worked out?
