I remember someone saying this would taint Monica's legacy--perhaps. But she wasn't successful. They could find a confession letter, where Monica said Drew needed to be stopped.
They can preserve her legacy by keeping it quiet. Drew's last act to honor the woman he loved as a mother could be to agree to bury it.
Heck, what if Drew was secretly meeting up with Jacinda for sex and promising her the world and then told her he can't be seen with a hooker. So she shot him. But then, how did she get the gun? 🤔
