Disecting the Gemma and Clay fight scene

Whilst in no way i condone domestic violence, but...
He could have (and surely would have) walked away if she had hit him with a frying pan or something, but she nearly blew his head off. And knowing Gemma, she didn't fire into the air just to prove a point. If he had just stood there, most likely she would have tried again and again.
He regretted it almost immediately.
However, he had been such a prick to Gemma throughout s4. When he grabs her by the neck in e2 or 3, it was obvious that this is not going to end well. He was very different character than we knew from s1-3, when he was just sweet and loving.

I'm not sure if the shot was ever meant to hit Clay, but seems to me, if the intention was to wound or kill him, she had time to fire again.
Point in his direction and empty the thing.

their gradual repair after that beating she took, tells the real story.
Gemma is reluctant to completely eliminate or even completely sever ties with, any man who might still come in useful to her.All possibilities for her avoiding ending up old and alone.

If she wanted Clay dead or even seriously damaged in hospital, it would have happened there, imo....some might point out that she may have had an eye on the broader political ramifications of Clay's death , to the club and business.

For his own part, he must have been firing wide too. Man of his size and apparent strenght, if he cut loose all-out on her in that kind of situation, he would cave her face completely in in a few blows, not just give her a couple of doozy shiners and fat lips.He'd pretty quickly kill her outright.
