You don't have to, no, but feel free to
I've voted:
Lilbro - for making me laugh numerous times across the series and an inspired Isabelle campaign
Vanessa and Littlegreen - for their support of Raph and keeping that train going no matter what the cost
Daniel-X - I was torn between Cal and Daniel-X, the bitter frenemies, and ultimately went for Dan because Cal won the CBB edition in January
and
Vicky - for sitting on the fence the whole bloody series and being a welcome 'middle ground' that this series probably desperately needed on here.
