What do you think Stewie would do if Brian died or left town?

If Brian dies, Stewie would be scarred for life like how I've been scarred for life since my best friend…quit on me? Abandoned me? Wasn't allowed to be my friend anymore? Yeah, that's it. Stewie would have an emotional breakdown…

He'd probally go after him in some crazy cross country adventure. maybe like the movie roadtrip. i dunno but it'd be funny as hell

I would totally cry.
