"Gganbu", the sixth episode of Netflix's breakout hit Squid Game, is probably the standout episode of the entire season. It doesn't have the grand theatrics of a giant robot doll or a killer game of tug of war but it doesn't have huge emotional gut punches. Here are some reactions and insights from people who still haven't been able to pull themselves together.
Sang-woo picking Ali as a partner was so strategic and calculated. They didn't know if they would be working with their partner or against their partner for this game. So, if it turned out the game required them to work together, Ali is reliable and strong as a partner. But if it turned out they would be against each other, Sang-woo knew he could outsmart Ali and take advantage of him (which is exactly what ended up happening). Either way, Sang-woo would win and move on in the games... what a sneaky bastard... This is probably also why he didn't partner with Gi-hun, in case it required them to be opponents.
There were a lot of gut-punches in this series, but I think the one that hit hardest was when the husband and wife had realized the consequences of their decision during Game 4.
Actually, everybody realizing all at once was terrible.
