I wouldnt call him a bully but sometimes he over does his silly jokes, but dont worry Candice is not one to take anybody´s shit but anyways, they get along fine, she always talks how funny he is on set and she just commented on his IG "Love ya, Tom" on the video that him and Carlos were singing to her.
I often see Tom smirking laughing and whispering whenever Candice is speaking. He's clearly mocking her. Even grant stepped up during a panel and told Tom to stop.
I understand you but I also think that is Tom's personality I have seen him act like that not only towards Candice but his other costars as well. I don't think he understand how it looks and how other people could misunderstand him for bing rude. I think he's nice but I agree with you that he takes it to far sometimes.
