After the phone call with his family, Jamal decided to make one last group call to his friends so he wouldn't have to repeat the story to each one of them.
He knew by informing his mother, his stepdad would hear it from her. He also knew that his grandmother would hear from his grandfather.
Now that his aunt knew, Mari would likely hear from her too, but he would rather tell her directly because she was not just family, but a dear friend to him.
He knew he still needed to return her call concerning the issue she had texted him, and he also needed to return Emily's call concerning her issue, and he was yet to check on Callan and bring him up to date with his plans.
Unlike Mari and Emily whom he had told about seeing Genevieve and becoming her driver, he was yet to talk to Callan about that, so that would mean having to explain more of those details to Callan.
