Can someone please write an AviSynth script to do this?

The detail that was "fixed" simply does not exist in the before picture.
Hehe, I don't even see what was fixed, unless it's that frame thing to the right of the guy. The before looks kind of unclear and jaggy while the after is more precise, or something. In any event, if that's it, you take a good version of it from the previous or next frame and replace the bad with the good. Not hard and any photo editor can do that. Then you simply replace the bad frame with the good in the script. The number is the frame number to be replaced, and the fixed frame is given that number.
ReplaceFramesSimple(Last,Q,Mappings="42402")###Rep lacing Edited Frame
ReplaceFramesSimple is a part of stickboy's RemapFrames. You might also be able to interpolate a good frame from the two good frames before and after the bad frame. It doesn't look like there's much movement so it should work well. If there's no movement, BadFrames will work well.

"so with stock footage from other episodes..."
The script would depend on what episodes or footage you have available , or you can use other tools (probably better for this type of repair, because it involves compositing)
You need a deblocking filter followed by QTGMC(InputType=1) or a temporal noise reducer. Or for individual frames you might consider replacing them with a frame motion interpolated from the frame before and after. But you'll have to locate the frames manually. Upload a sample of the source (don't reencode).
Would it be helpful for me to use anti-aliasing?
If yes, what anti-aliasing?
By the way, have you seen the great job with sharpness on the same thread?
And AviSynth script used
I think what they did was take those messed up scenes/frames and replaced them with scenes/frames from another source of the same movie. I believe what they are calling fixed is the issue they mentioned the video had, by them doing the frame replacements from another source or different parts of the same source.
