Remus - 5
For one heat-stopping moment Remus had watching Regulus head toward the fray. But, after seeing Regulus' trajectory, he understood the behaviour. He'd just have to trust his lover knew what he was doing because Remus' skills were needed elsewhere, no matter how much he wanted to be there to make sure Regulus was protected.
There were others here less capable that needed help.
Manoeuvring around the chaos, he concentrated on defensive spells, throwing barriers between birds and their targets, buying time for others to get the wounded up and out of the line of fire. It was inevitable, he supposed, that the four of them end up fighting together. As the last of the wounded and vulnerable were escorted past them, he realized it was down to the four of them covering the last of the stragglers' escape.
Dirty, covered in minor scrapes and bruises that would be mere memories by morning, Remus dodged a spout of flame just as he saw James go down. But, he didn't have time to do more than call a quick "All right, Prongs?" as his friend got up to rejoin them. A flash of movement out of the corner of his eye took his focus. He could see Sirius holding his own, but two of the birds were descending on his from behind. They were too far apart for Remus to get them both with one spell.
"Pads! Look out!" Remus blocked the nearest one, while simultaneously flinging himself between the second and his best friend. The sensation of sharp talon-tipped claws tearing into his exposed, wolf-bitten shoulder was painful. But, what was one more set of wound scars? He'd heal. Reaching over his shoulder, he took the bird by the neck and wrenched it up until it loosened its hold on his flesh. Then, he flung it away, using the motion to snap its neck in the process.
It was as he turned to make sure Sirius was okay that he felt it. The surge of searing pain, like fire in his veins, and the sudden awareness that something was horribly wrong washed over him just before all his strength failed and his knees buckled, sending Remus tumbling to the ground.
