What's interesting with Xie Zheng regarding his relationship to Changyu and especially the people around them is that he really is trying to keep himself in check. He does not use violence, stay calm, does not uses his identity as a husband to undermine people.
He does not hide his identity as a husband, but he is subtle about it.
He tries to show his relationship to Changyu through actions, and subtle ways of caring. He is a devoted husband behind closed doors, but in public he tries to be subtle.
However whenever he feels a "danger" approaching he will uses possessive determiner (my, her)
First example is when she is injured and he finds her in the snow. She needs medical help. The old woman says I cant help her as I am blind and there is no woman. At that point he is still hiding/protecting Changyu from his identity. But danger (death) is imminent so he uses his identity to help her and save her.
There is another case where he will uses it possessive determiner.
Whenever he feels that someone, a man, is too close to his wife he will use "My wife" as a weapon.
We saw it in yesterday episodes when Wen Kan said "I can protect her". Xie Zheng does not tolerate him speaking like that about his wife, so he uses the card "my wife"
He is showing proudly and reminding him his place. He is the husband, and Wen Kan is just a colleague. That side of possessiveness often comes out around Wen Kan. Remember in Lin'An when they met and he told not him not to fancy his wife.
In today episode, we saw that he was keeping quiet. Sitting calmly next to Changyu, reminding people of his identity as a husband subtly. However when her aide is like I admire you, I'll always follow you, lets drink, he cannot stand it anymore.
Xie Zheng is stepping in, not only because she is already drunk, but also because he can feel that the aide's feelings are not platonic. He needs to remind people that she is his wife. And not to step in.
He knows that Changyu does not want him to physically hurt people (the butcher in Lin'an) as it could have bad consequences for him.
So he has no choice but to uses subtle ways to remind people of his identity : his demeanor and most importantly his words.
