In the season finale, Nathan leaves the Bahamas to undergo emergency surgery on his vocal cords. With his mom by his side, Nathan is optimistic about the results, but worries about missing out on months of performances. Later, the band travels back to the UK for a show at the historical Wembley Stadium, but Nathan's vocal coach warns that the timeframe could be too soon and perhaps could do more harm to his voice. The band's future seems even more in jeopardy when Max lands a movie role and Siva no longer has the support of girlfriend Nareesha while on tour. Will the group split?
