Sev and Lucius
Lucius was furious. The attacked was well planned he had to give them that - which of course meant it wasn't them who had planned it. Someone who knew where the village was...there was only one possibility. And he wanted that man dead.
Ordering a lower Death Eater to get the anti weapons spell up, and a few others to protect the caster, ready to take his place if he was lost, he set off into the battle.
'Die to protect him if needed!' he shouted at them just before taking off. The mask kept him from being a main target, and he fought his way through lesser skilled fighters in search of the one he really wanted.
Severus!
Spotting a movement that he knew only too well, he set off, moving in a circle and aiming well before sending off the first hex. He hoped Severus wouldn't see it coming.
