In a/b/o!overwatch with r76 how would jack react to gabe being an omega and jack being an alpha?

I would like to talk A/B/O with y’all but it’s sometimes difficult for me to answer them because… what would he do? He’s in the military and a special program. he’d probably do a double take; maybe look at him funny every now and then. but overall he wouldn’t react in any special way, I think
