The ep was up for download in the usual places on Monday night for some reason. It was ripped from CTV, a Canadian network, but that often happens for American shows, sometimes because they air earlier the same night, sometimes because the person ripping them happens to live there. I don’t usually watch on live TV or even official streaming apps, I just keep an eye on the download list and get what I want, so I originally assumed it’d aired in the US as well. Maybe they just aired this ep early, OR, they air a few days later than the US and it just so happens that it was the US that missed its airtime last week?
Regardless, it’s up there if you know where to look.
