"throw a case back with" meaning?
Dave and Ron are good friends.
Dave,
Heyo. I got your note about "needing to talk" and sorry I didn't track you down. Been looking for you all day; figured you'd be out near the canyon helping those grad students but I guess not.
I don't even know how I could really help, anyway. We're coworkers, ya know? Amigos professionales. If you need someone to _throw a case back with_ and go time-traveling, Ron's your guy. But I'm not great with the life stuff. You get it.
Later,
Ron
This is a note from Ron to Dave.
I don't understand "throw a case back with". What does it mean? Thank you.
