In the last episode, while they were talking about the rule not to show physical affection while the other women were present, Christine mentioned how Kody would give them flowers and kiss each of them in front of each other. Here are just a few instances of it, lol
When the women were leaving for their California trip, he kissed each of them in turn.
On Meri’s birthday when he lifted her a second Mexico trip, he kissed her in front of the whole family, including the other wives.
That time he went to Christine’s to see if she had parts he could use to hang Janelle’s TV and had Robyn bring her parts over too, he kissed Christine before he left and then Robyn followed after him to get a kiss too
After getting the keys for Christine’s house, he prepared to leave with Robyn and kissed Christine in front of her.
When they went out for a family dinner, Kody was going to go home with Christine, so he kissed the other three in full view of each other before heading home with her.
There are many other instances, but I think I'll just leave it there.
