As Indy said - you can't put a lot of weight on anything said under the influence of medication or late life stages. His mind was no longer his own thoughts.

And, the things his coworkers said - well, it could have been misinterpreted to a point as well.

It never fails, there is always surprises from things people said to others. You need to keep your eyes of what is was between you two only. You will make yourself crazy trying to analyze these things. And really - does it matter? - I don't want you thinking any of these negative things. It won't help anything. It will take you to a dark place - you don't need that.
