♥: How they show affection.
Riella shows affection one of three ways: through cuddles, through being (over)protective, and through being the epitome of the Sarcastic Sidekick. So if she’s curled up on the couch with you while making deadpan comments about your need to be more careful, she really likes you.
☻: Person who could without a doubt make them happy.
Heavily verse-dependent. There are bots in specific ‘verses who could, without a doubt, make her happy or at least content (Prowl in (Un)Attached comes to mind), but there’s no one in her main ‘verse. Some bots have a better chance than others, but it’s never guaranteed.
✖: A trait they despise in people.
People who hurt or threaten someone who can’t effectively fight back for whatever reason. If you pick on someone weaker than you are, it will make her angry. No exceptions.
(Note that this usually isn’t aimed at people who hurt her. Regardless of relative size, rank, or physical ability, Riella very rarely sees herself as helpless or incapable of defending herself.)
