1. Is it at all possible that with Mr.Panucci's hendering health and his failing buisness that Seymore may have just outlived Mr.Panucci?
I don't know what "hendering" means, but sure, it's possible.
2. Is it just me or does Mr.Panucci age alot for only 12 years?
I dunno. How old was he to begin with?
3. Mr.Panucci tried to feed Seymore possibly leading on that he cared much more about Fry then he led on?
Why shouldn't Mr. Panucci try to feed him? Fry wasn't around, and the dog was always sitting on the sidewalk in front of his pizzeria. Someone had to feed him.
Also, I'm not sure what you mean by caring much more about Fry than he let on. Mr. Panucci seems to treat Fry pretty well for an employee.
4. Considering Seymore knew exactly were Fry was do you think it was possible that he waited just because he felt guilty?No.
He waited for Fry out of loyalty; not guilt or stupidity or anything else. Loyalty. If you don't understand that, then I don't know how to explain it to you.
