The OMC LRR from EP - always AA/AK and never AK/JJ?

1/3, 9 handed. $500 max. Early Friday night, like around 5pm.

$6 straddle UTG. Nitty OMC limps in UTG1. Some more limps. Hero (MAWG/TAG running well since he sat down) raises to $40 in EP with QQ.

Folds around to the OMC, who 3B's to $140, leaving about $300 behind. Folds back around to hero.

Hero?

Kind of an obvious spot, when the nitty OMC limp-3B's for almost 1/3 of his stack, right? Gotta be AA or KK, right?

Does anyone believe he might have AK or JJ here?
