X-Files & wife getting eaten!

[retroborg]

I vaguely remember watching 5 years ago an X-Files TV episode, where there was a guy that participated in a grotesque experiment. If I remember correctly they had an Alien / monster thing stitched up inside his esophagus / stomach!
The thing would come out of his mouth every once in a while to have a “snack”.

His wife was a bitch & would quarrel with him all the time. At some point they were in a poorly lit basement beneath their house & the wife would go on quarrelling about some shit. Then all of the sudden the monster inside him, probably got fed up with the never ending nagging & decided to take immediate action. It got out of his mouth & ate the wife while she was screaming in terror.
At that point the camera view was from the outside of the basement door & you could see the shadows from the scene of the wife getting eaten & hear the screams of terror & agony.

I don’t remember how the episode ends, but I was wondering if anyone knew the name of this specific episode or the exact year / season it was released, so that I can look it up.

Thanks in advance.

Sounds like Season 5, Travellers.

Was it set in the 50's, or many decades in the past?

I don't remember?
