To be honest? Half of Waver's CR started because he couldn't Shut Up. It's hilarious, because he will argue over the stupidest crap!

That said-- how much around town was your kid in Sanctuary? Waver's keeping an eye on everyone he knows that comes from that town, whether they realize it or not. It's just a practicality thing-- he's a Magus with the Analyst skill and a very healthy dose of Paranoia.
