Regulus was talkative, he would often go on and on about trivial matters in the most incoherent ways, usually leaving the other party confused and/or unable to follow his thoughts, ideals and values. If his opponents had said something that went against his opinions and beliefs, he would find unreasonable faults in them, gradually becoming angry while accusing them of "violating his rights". He took everything as a personal assault and critic, which made him feel like everyone was against him.
