Saibu's value couldn't be exhausted overnight, so Gao Yi had time to look for that arms dealer while waiting to interrogate Saibu.
He couldn't go himself, Grins wasn't prestigious enough, and even George showing up personally wouldn't work, simply because the Secret Action Bureau's presence had been too weak in Baghdad previously.

Grins's words wouldn't work, but with just a word from George, the Iraqi Military would have to send someone influential to accompany Gao Yi.
