The Great War, James had ran out of the castle and thrown a spell at a death eater, knocking off their mask that suddenly revealed Regulus…

“Regulus!” James shouted as he ran over to him. Regulus’s head shot up as he was clenching his stomach. “James?”

“Reg, c’mon!” James said with a hint of concern in his voice. “What about them?” Regulus responded, talking about the death eaters. “It doesn’t matter, they don’t own you.” James said as he then grabbed Regulus’s wrist.

“Fine..” regulus said.
