To be honest Reigns is most likely going to retain his championship in the Rumble, thats if HHH doesn't make his return during the event. Brock Lesner just might end up fighting Bray Wyatt at WM if thats the case leaving Triple H to face Reigns for the title in a No DQ match, where a shit ton of people will most likely get involved with all help for Reigns bared from ring side unless he wants to automatically lose his championship.
