As gleeks old and new pitch in to help get ready for Brittany and Santan's wedding, the happy, albeit nervous couple settles on a few final details for their upcoming nuptials. The planning stage hits an impasse, however, when the two brides have a stark difference of opinion over whether or not to invite Sue. While Brittany, who credits Sue with bringing them together in the first place, is in favor of extending an invite, Santana is vehement about refusing to allow Sue's attendance. But the former Cheerios! Coach is not so easily dissuaded and still has a few characteristic tricks up her sleeve. And the supremely superstitious Brittany is thrown for a loop when Santana sees her in her wedding dress before the big day. Meanwhile, when Kurt and Blaine finally reunite as a couple they are all too aware of the mistakes and regrets of their past, but supportive words from family and friends inspire them to take a sudden and daring leap, and Tina announces her unorthodox decision to ask former boyfriend Mike Chang to marry her, but while most of her guy friends are supportive, fellow former flame Artie remains dubious about the plan.
