The revelation has Venom letting out a quiet "oh" before continuing to watch. This memory must be older than Venom thought, but it makes sense, considering Justice's existence as a spirit.

"At the very least, you had a positive impact on her life. I think she wanted you to know that, despite how this memory began." It was probably little consolation, as Venom knows he's not the best at comfort, but he hopes it helps.
