Well... Thought it strange that noone even mentioned Linda by name in Episode 4106 with Samara as part of the focus for the episode's story.
Would love it if they brought her back, then maybe they could finally create some closure and present a family dynamic by having Bob and Linda together again, interacting with Samara.
Although, the reason I'd like to see Linda return is cause to me, personally, she's one of my main personal heroes.
The last episode I know she was in was a Season 30 episode where Snuffy wanted to give Linda a birthday dinner for her and Bob.
Bryan, it would be difficult to get an interview out of Linda Bove. Reason I say this is because she was not only deaf, but deaf-mute. At least, from what I remember of the later progression of the character...
There was a segment where she was trying to sound out some words with Bob on the stoop, and Oscar helped out by overhearing them and trying to get Linda to sound out some grouchy words like "phooey".
In another later season, there was someone else providing an inner thinking voice for her, don't know when nor how long this lasted.
Hope this helps though.
