The jumpseats are most likely aft, since the radius of the perimeter of the bulkhead is small, and if that is a passage to the left of #3, that is a pair, possibly even on the aft pres bulkhead. (~unfamiliar 330) I'd like to again point out the stowed harness/belts, they were not occupied if Captain had ordered seatbelts and FAs to sit secured in the turbulence.
