Is there a second encounter with Trevor's Mother?

So I found the Deludamol Van outside a hospital in LS, drove it back to Trevor's house for her mother but her mother isn't there anymore.

Now this is apparently "The first encounter" pointed out on the IGN GTA5 Wiki

The second encounter for the wiki says "Please check back later"

Since the main storyline is done I really want some closure (if any) for Trevor's Mom. Does anyone know if the story continues or this "second encounter" doesn't exist?


Multiple sources indicate that

Trevor's mom never appears again after the mission you mentioned.
