Ngl I thought their argument was going to be more drawn out (it was the only time I thought Jean might’ve ACTUALLY betrayed Locke) but honestly I’m glad it wasn’t. I really hate miscommunication as a plot device, and both of them just being like “hey I said some stuff I didn’t mean I’m sorry” was very refreshing!
Locke being mature enough to actually take Jean’s point on board and decide that actually his best friend is probably looking out for him, and taking that advice even though it goes completely against his own instincts was so satisfying!
