The reunion episode is definitely still available.
First option as soon as you select channels and Sky Max.
@parrotmad yes it's still available but not showing when I search on my Roku device so I'm assuming it won't show on some other devices like the Now stick or box.
Depending on your device, on the home page go to and click on entertainment, scroll down to channels and then scroll across to Sky Max. Click on the channel name and you'll find it in there.
Alternatively, if you have Now on a mobile device you can find it by searching, add to watchlist and then it will appear on your main devices watchlist.
Also when I searched for the show.
