- "Very well. Get your cousin out of here, girl. And if he comes to, remind him that the next time he poaches off the Capitol's land, I'll assemble that firing squad personally."
- ―Romulus to Katniss Everdeen[src]
− Harsh and unforgiving, Thread appeared in Catching Fire, ready to enforce the law, no matter what. Being fiercely loyal to the Capitol, he was willing to do whatever it took, going to such extremes that he injured Katniss, the victor of District 12 who had an upcoming modeling session.
Upon arrival, Thread brutally beat Gale Hawthorne, who had been caught poaching a wild turkey (for pushing Thread away from beating someone, in the film). Although Gale had been selling meat to the Peacekeepers of District 12 for years, they turned a blind eye to this illegal poaching, since they were his best customers. Gale went to sell the turkey to Cray, Thread's predecessor, when he unexpectedly found Thread at Cray's house. Thread saw Gale's poaching as a flogging offense, and threatened to kill Katniss or Gale if he saw either one of them in the woods. Darius tried to intervene after about 20 lashes by grabbing Thread's arm but was struck in the head by Thread, knocking him unconscious.
After that display of cruelty, people stayed inside their houses, rather than risking the wrath of the new band of Peacekeepers, including Katniss. A few days later, however, Katniss crept out of her house and headed to the woods where she met Bonnie and Twill. Upon her return she found Peacekeepers sent by Thread to deliver a message: the fences will now be electrified 24/7.
Romulus was seemingly rather fascist. He was ruthless, pitiless, violent and masochistic. He was also cruel and vicious, not caring who got hurt during his military activities. He carried out his orders without mercy and without compassion, making him somewhat sociopathic. Romulus Thread was an idealistic, angry and powerful man who seemed to terrify everyone with his mere presence. He was also very aggressive and declared that anyone caught breaking the curfew he organised in District 12 will be shot on sight.
