He already had it, but the alpha was gonna bite him so that's why he apologized ( ̄∇ ̄")or well I think so..... Beth
Oh right, I checked the raws and it makes more sense...
SPOILER . . . . . . . . . . . . . . . . . . . . . . . . . . . . . so the omega was already bitten by his husband who died... so I guess he can be bitten again in this case? I always assumed omega can be bitten only once.
Wait I am confused... is he the one who bit him or did he already have a bite mark?
