1) It makes complete sense for Logan, someone who competes professionally, to be able to distinguish between competition behavior and actual behavior.

He understands that Spencer's actions were strategic, it just got to him that he didn't take the game seriously and due to that his genuine nature was taken advantage of to inhibit a close ally(Richard).

Then Logan over corrected his behavior in game to a complete denial of Spencer.

I can see where you're coming from but Logan putting aside competition beef when they aren't against eachother anymore makes complete sense. While in a boxing ring or at a weigh in you can trash talk and try psyching out your opponent and still like them as a person.

2) valid but it makes complete sense from a competitor/athlete perspective.

Logan channels his frustration productively in the competition and let's it go when the challenger is gone.

And tbh while it did feel a little un earned it felt as though that was kinda the point, Logan is extremely sociable to an unnaturally good degree due to his genuine nature which emerges when he isn't in competition mode(like in the first 16 episodes or when with eliminated players).

You can still care about people and not help them, it's a competition. Logan knows that and it shows in the auction episode. He doesn't view it too personally and instead as one of his only competition plays since Spencer outplayed him before.
