"Thank you. Now," James clapped his hands together, grin bright as the day Regulus had met him at King’s Cross. But Regulus could see the strain around the edges. The tension in his jaw. The bone deep sadness that probably ached just below the lifeblood pumping through his veins. "Someone explain to me why we’re in hiding." Straight to busines and he would smile through it. Regulus prayed that Sirius would teach him how to grieve some day. Because Regulus couldn't. James may not have known how to grieve. Regulus simply wasn't allowed to.
