1) Only reason he's not going after Rollins is because he still hurt brehs. That was his brother. Roman was always more passive than Dean as evidenced in their Smackdown Summit after Rollins walked out on them during Shield vs. Wyatts on RAW. Dean was ready to drag Seth but Roman was willing to give him the benefit of the doubt. Brothers might turn on him but it's still hard for him to obliterate his family.
Also, he knows Ambrose can handle his own. Where was heroine Dean when old Romey Rome was getting the beats from 3MB?
OH THATS RIGHT. Sitting in the back waiting for his match against Bray.
2) Authority trying to take him out multiple times with HHH personally going hardest on him. Stephanie guilty by association. Also are we gonna forget that she stood on the stage and sent the locker room after The Shield a few weeks ago? You gotta do what you gotta do to get where you wanna be and it's always easiest to run through those who've already wronged you.
3) He's helping Vicki retain the bit of dignity that she has left. Like he said, she's a Guerrero. She shouldn't be no one's errands bytch. He knows her worth even if she don't. So thoughtful.
4) It's tradition. You don't break traditions. Ryback will be catching spears, curbstomps and Worldstar beatdowns until he gets the deavors.
5) He doesn't adjust well to change. Hence keeping the vest, the theme and the aforementioned tradition. Shouldn't you be saying the Dean was quick to drop Roman as soon as things went south and he had a new target in mind? :Anoai:
Even if he were a scumbag, he's my scumbag.
