best performance of the episode. Brian Moyler of Gawker, who writes of his dislike of mash-ups, characterized it as "the only mash-up of the night that actually makes sense" but he called it an "awful aural clash" and "the second least dreadful". Moyler felt that the combination of "I Can't Go for That" and "You Make My Dreams" was "an abomination" and "New Directions at their worst". He summarized: "The outfits are hokey, the dance is silly, and the music has absolutely no emotion in it." Slezak, however, issued the performance an "A−" grade, and wrote, "The Troubletones beat New Directions in this particular battle, but I loved the frothy, silly spirit of this number, with the guys dressed like Miami Vice extras, Puck and Blaine rocking Oatestaches, and Tina getting a little moment on lead vocals." Votta characterized the performance as a "fun, retro number", and Jen Chaney of The Washington Post was similarly pleased, and gave it a "B+". The episode's concluding musical number, "Rumour Has It" / "Someone Like You", was acclaimed as its main highlight. Raymund Flandez described Rivera's vocals as "electrifying" and "golden". Futterman wrote that the performance was one of Glee best sequences: "Mercedes and Santana nail their vocals and the song combines great tracks from one of the year's biggest albums while capturing both the sass and sadness of the Troubletones at this particular moment." Votta called it the best performance since the cast's rendition of "Don't Stop Believin' in the season one finale, "Journey to Regionals", and stated, "Naya Rivera's powerful vocals and the strong arrangement still packs the emotional punch Glee was targeting." Chaney awarded the sequence an "A+" grade: "Given the emotional stakes raised by Santana's outing, which happened in the scene right before this performance, and the fact that it marked the series's 300th musical performance, this marriage" of the two Adele songs, "Rumour Has It" and "Someone Like You", was "all the more powerful". Moyler asserted that the number was "perfection" and said, "This is why I watch Glee. It is just brilliant from Mercedes first belting to the snaps on the beat to the choreography with the girls walking in a circle and making little whispers to Santana bringing tears to my eyes singing 'Someone Like You' as if it was the last song she'll ever sing in her damn life." Cinema Blend's Melissa Duko stated that
