True, the slap shouldn't have happened, but we should consider that they literally had a fight over the exact same thing a few chapters ago! remember that, when Gain was hospitalized and the alpha (sorry can't remember his name right now) was worried to all hell and didn't know what was happening? Yeah, when Gain literally said that that thing wouldn't happen again? No wonder the alpha was so hurt by that

Accidental or not, that Alpha should have had his conclusion jumping arse handed to him. That really pissed me off.
*vent over* I can't wait to see their child! ε=ε=(ノ≧∇≦)ノ Hope they have more than one child. Just a big arse family (๑•ㅂ•)و✧
