"Poison": The obvious poison was Will himself, who decided that having never pursued his own youthful singing ambitions, he needed to follow his dream to perform. That lead him to create the Acafellas, the world's first all-male music-less hip-hop review, with thumbless shop teacher Henri, coach Ken, and Sheets and Things clerk Howard. When a performance at a local restaurant lead to an invitation to sing at the big PTA meeting (and this was bigger than even the mom-crazy gatherings in Park Slope, so that's saying something), Will forgot all about why he started coaching his choral castaways and focuses all his energy on his new project.

Of course that led the remaining Glee kids to head off in search of Dakota Stanley, the best show choir choreographer in the Midwest—which is something akin to being the best baton twirling instructor in the Northeast. Dakota is much meaner and shorter than any winner of Little Miss Twirl, and his insistence that the choir members change their appearance and diet doesn't go over so well. The poison is sucked out more quickly than if Finn got a snake bite in front of Rachel and Kurt, and the crew decides that they'd rather have their uniqueness than a collection of snazzy lifts, dips, and ball changes from Dakota.

Also dripping poison in the porches of ears were the cheerleaders, who are on a mission from Sue Motherfucking Sylvester to disband the group so that she can purchase a fog machine. They latch on to lonely Mercedes, coaxing her into going after obvious babygay Kurt. It does not end well.
