In the latest episode of AMC's "Into the Badlands", titled "White Stork Spreads Wings", it seems after finding out the plans of the Widow, Quinn decides to have his vengeance against her.
According to the synopsis of the episode, as Sunny begins to train M K, the boy struggles to learn discipline. Meanwhile, Quinn seeks retribution against the Widow and faces the consequences.
In the previous episode titled "Fist Like a Bullet", after wandering into the Widow's territory, M K met her daughter Matilda, whom he followed for refuge into her mother's mansion.
However, it turned out to be a dangerous place since she wanted to use his dark power to overthrow the other barons. Meanwhile, after Quinn's headaches were diagnosed by his long-time doctor as a tumour, he wasn't given long to live.
In order to keep this news a secret, he ordered Sunny to "clip" the doctor and his wife, Veil's parents, who know about their unborn baby. However, Sunny refused and Quinn had to murder them himself, which gave him a second chance to test his loyalty.
Later, when Sunny and Ryder were attacked by the Widow's nomads, M K saved Sunny's life and agreed to show him the way out of the Badlands. But Sunny had a condition: He would bring M K back to The Fort for training so he could be strong enough to smuggle Veil and the baby out.
Previously, Regent Sunny, a highly-skilled fighter and the deadliest "Head Clipper" for Baron Quinn, battled the Nomads to rescue M K, who harboured a dark secret about his past. But when he brought him back to the Fort to train as a "colt" — a Clipper-in-training — things quickly got out of hand with another trainee.
When first blood was drawn, M K lost control of himself as if something took over his body, making the boy valuable to opposing Baron Widow.
