During the early rescue scene in Furiosa (2024), Fang snatched the gun from Mr Harley to fire it at Furiosa and her mom. This demonstrates that Mr Harley has always been sympathetic towards her, not just at the end, even though he’s a very small character

Mr Harley is that guy Dementus chews out near the end for not wanting to hang Furiosa up by her mangled arm, and thats really his only major scene, so some theorize he helped her escape since he seemed sympathetic towards her.

During this scene, it’s a blink and you’ll miss it moment, but he hesitated to shoot the gun at little Furiosa and her mom, so the much more ruthless Fang snatches the gun and shoots them himself. Mr Harley and Mr Davidson seemingly have a loving relationship, so it seems likely he’s one of the few bikers with compassion. He also looks very uncomfortable when Furiosa is traded to Immortan Joe, and Mr Davidson comforts him

Heres a great thread on all of Mr Harleys little scenes
