MuchMusic posted a press release with its network highlights for the month of April, and accidentally posted the episode description for the Season 12 finale, The Time of My Life (SPOILER ALERT BELOW):
Imogen can’t imagine saying goodbye to Fiona, and resorts to desperate measures to try keep them together. Clare attempts to move on with her life without Eli, while Mo wants to lock down a “bromance” with Jake before the summer.
It says the episode airs this Friday, but that’s obviously incorrect (Zombie Pt. 2 airs tomorrow). The Time of My Life will air as a one-hour episode sometime in June or July.
