Possible force feed scene?

Does anyone know about a tv show called Grimm? I really don't watch any of it, but shows about strange mythological events happening on earth, most of it dark natured but pretty much kept at a PG/13 level. Anyway I saw a program on scenes of a future episode (sadly I don't know the name). During the clip there was a guy who kidnapped a woman and has her in a cabin on some forest. She is strapped onto a chair, a tube shoved in her mouth and some large milk jar (not to mention the flick of a switch). I'm not sure what comes next but I can't shake off the feeling that the woman would be forced to drink lots of milk. The big issue is that I don't know what is suppose to happen to her, but if I am not mistaken it will start on Direct TV tonight at 9 or 10pm (at least from my location). The channel is 218, "Universal" (The blue "Universal" nameplate with the 'earth' logo graphic behind). I'm pretty sure this episode was already hosted on local US channel but it is new on Direct tv.

I'm still investigating online but I will try to watch the show tonight, just can't promise anything...
