AQs in the sb Pre-flop cold call

[Frogic]

A friend of mine whose full table prowess I respect played this pf a bit strange(well atleast to how I play). What do you guys think?

UTG+2(15/9/1.36) open raises, folded to hero in the sb with AQs, bb is unknown and Hero calls.

Oh also table image wise, Hero says that he raised three hands in a row just before this and lost them all.
