Poso was an intelligence officer in the Navy so he is definitely in the know. It wouldn't surprise me if he really is Q and justs trolls to through the DS off.
He speaks fluent Mandarin and Arabic with some standard Aramiac. He may have a face that looks like he is always taking a shit but he is a man of many hats and talents.
He's an AJ ass-licker and also loves Fauci and Gates and can't wait to be the first in line to take ol' gatesy boy's vaccine.
