For reference, from the images in Table's earlier link:
"Keeping a Close Eye on You": "You may look at one played Mission card".
I believe that the way this works, after a mission, you can use it to look at one person's vote.
"Take Responsibility": "You must take a plot card from another player" .
I'm not sure whether this applies to plot cards already used up. If it applies to one-time use ones that have already been used up, then I think it's obvious that using it a a second copy of "open up" is the best course around. Of course, I'd rather have it than cayvie, or, even better, give it to somebody closer along the line of succession; Cayvie's not going to be proposing any missions for some time, better use that on someone who's coming up in a bit. So maybe Grujah or Axxle.
If you can't use it to redo 'open up', then all it does is pass around the Opinion Maker or maybe the "Keeping a Close Eye on You" if it applies to that.
