|“||I joined the Merchant Marines, sailed the seas, desperate to outrun the Blossom curse.||”|
|— Claudius to Cheryl Blossom[src]|
Claudius and his twin brother Clifford were raised in Riverdale. Years later, Claudius would describe them back then as "a modern-day Romulus and Remus". Eventually, however, it became clear that their parents were grooming Claudius to inherit the Blossom business empire. On their 14th birthday, while down by Sweetwater River, Clifford threatened Claudius with a rifle, telling him of the "Blossom curse", in which one twin often met a violent end, often at the hands of the other. Although Clifford spared Claudius' life, Claudius was terrified enough to run away from home that very night. Claudius joined the Merchant Marines, and traveled the world, hoping to avoid the family curse.
Claudius' disappearance devastated his mother, who could not even bear to speak his name. Clifford, who went on to inherit the Blossom business, never even told his children of Claudius' existence.
Returning to Riverdale
After decades away from Riverdale, Claudius returned during the reading of Clifford's will. The arrival of Claudius, a man who looked identical to her despised, and deceased, father, caused his niece Cheryl Blossom to faint in shock. When she came to, Claudius explained his history to her.
Sometime later, however, he expressed disgust with the Lodge family and a desire to get revenge on them. His sister-in-law Penelope Blossom, however, reminded him of a secret agenda, saying "first Nana, then Cheryl", unaware that Cheryl was outside the door listening.
That morning at the breakfast table, Cheryl claimed that someone was trying to break into her room the night before, however, Penelope dismissed her claims by insisting that she was merely imagining things. Onto more important matters, with Claudius in town, at least for the time being, Penelope suggested that they start considering him in taking over Nana Rose's stewardship of the maple syrup business. However, Rose refused to even entertain the suggestion, and so Claudius offered Rose some of Penelope's special blended tea to calm her.
That night, an ambulance had to be called after Nana Rose suffered a terrible fall down a flight of steps, and fortunately, she would recover. Claudius and Penelope told the police that Rose suffered from Sundowner's Syndrome, causing her to lose her senses at night fall, which must've resulted in her fall.
The town gathers for Midge Klump's funeral to pay respect. Cheryl sings a song in Midge's honor. She and the rest of the River Vixens are dressed in all-black cheerleader uniform. Midge's death has seemingly taken a great toll on Riverdale, Mrs. Klump and Moose especially. Claudius stands alongside Penelope as the service commences.
A clandestine meeting is arranged between Penelope, Claudius, and Hiram in one of the old barns on the Thornhill estate. Penelope checks outside after they hear a noise by the door, but she discovers nothing. Little does she know that Cheryl is hiding in a barrel.
The next evening, on the other side of town, at the Whyte Wyrm, Hiram calls a meeting with all his accomplices i.e. Penelope, Claudius, Penny, Malachai and Sheriff Minetta. It's been months in the making but the time has finally arrived. Hiram welcomes them all to the new Southside. Penelope asks about Hermione, who Hiram explains can't be privy to certain machinations now that she's mayor. But the plan remains the same. The prison will soon be up and operational, with Claudius' drugs running through it. "Like brother, like brother", Penny comments. Malachai and his Ghoulies will be their soldiers and dealers, with Penny troubleshooting. And hopefully, doing a better job than she did of killing Jughead, Hiram remarks. However, as Penny explains, he wasn't breathing when they left him. Penelope reminds Hiram that he promised her a brothel, which Hiram intends to make good on. As for Archie, Jughead, Betty and Veronica, they are not of concern as far as Hiram is concerned as steps have been taken to tear them apart.
Claudius arrives at the Sisters of Quiet Mercy in the Blossom Maple Farms truck. This is odd as the Sisters don’t serve maple syrup in the cafeteria. Unbeknownst to Claudius, Betty is watching from afar, becoming ever so suspicious of the Blossom's connection to the Sisters.
At the Pembrooke, Claudius and Penelope inform Hiram that the Sisters of Quiet Mercy asylum is up for auction. It appears to be a competitive situation with multiple bidders, including the Farm. Hiram however has other plans for the property, which doesn’t include Penelope’s brothel. The reason Hiram summoned them is because they need a new sheriff, and he’s nominated Claudius, who initially refuses as the last sheriff was killed, but is strong-armed into the position by Hiram.
Claudius is instructed by Hiram to meet with Tall Boy to pick up Archie, who Tall Boy claims to have captured. However, when Claudius arrives, he is ambushed by Archie, Jughead and FP, and is then taken to the sheriff station and locked in a cell, where his body is later found.
Claudius is middle-aged man of average build, with pale skin, blue eyes and unlike his twin doesn't hide his prematurely grey hair under a red toupée. However, despite being Clifford's twin, his appearance is still enough to shock people, like they're seeing a ghost. Unlike other members of the Blossom family, who tend to favor wearing an expensive red wardrobe, Claudius typically wears casual clothing, such as turtle necks and sweaters, predominantly void of bright colors. However, in the night, he is seen wearing lavish silk pajamas originally of his brother's possession.
