Why didn't Wrath have Marissa's name carved on his back?

Marissa was Wrath source of feeding, but he never mated with her. Everybody thinks that Wrath and Marissa were mated but in fact they weren't even though at the beginning she loved him she only gave him her blood, so he would be able to survive. He never slept with her ou loved her to begin with, Beth was the female that brought these feeling out of him for the fist time. With Marissa the words "MINE" and the bonded male feeling never came out, with Beth they came out as soon as he meet her just has bonded male should when they find their mate. Besides Wrath and Marissa were never officially mated on front of the Scribe Virgin hence the point he didn't l’amour her. But with Beth, Wrath asked the Scribe Virgin the permission to mate Beth, hence he got her name on his back. And if he and Beth have kids their names would also be carved on his back blood signifying that they're blood from his blood.

my theory behind this is even through she was his shellan,he wasnt in l’amour with her and therefore never brought it in front of the scribe virgin.

Im thinking because although she was his shellan, he was not fully bonded to her

Because Marissa and Wrath never really had a ceremony of their union. Plus, he always thought that Marissa was to good and delicate for him. He wasn't really serious. She was just promised to him par his parents. They were just not right for one another.

Even though Marissa was technically his shellan, Wrath did not bond with her. I think only bonded males have thier shellans' name carved on the back.

THEY WASNT MATED!

Easy way to say it is.. They never did it with each other.

Because Wrath was never in l’amour with Marrisa, and therefore never mated her, he only fed from her. Marrisa was never truely his shellon.

Since Wrath thumbed his nose on the whole ascension thing it would follow that he didn't feel he was worthy to have happiness in his life when Marissa was promised to him. She represented all his failures as an unworthy son and male because he didn't save his 'rents (in his mind) so he didn't want to take his rightful place as the King. Remember the conversation between him and D, he's always felt unworthy, and Marissa being the eptomine of all that was worthy and perfect was like a slap in his face.

she was not mated to him par the Scribe vigin

In my opinion they didn't have a so strong relationship. Wrath and Marissa just drank in the other's neck, but nothing more. He didn't look at her as his wife.
