How do you tell who the extracted memories (facts, preferences, etc.) belong to?

[littttttlebird]

For example, in a companion app, the user (alice) says to the assistant (bob)："Yesterday my good friend jack said that he didn't like playing football, but his father enrolled him in a football training class. It bothered him a lot."

For this sentence, the memory extracted might be: "don't like playing football "," attended a football training class " or something like this。 However, these memories, which should belong to the third party "jack", will be remembered by alice on the spot in this project. How to solve this problem?
