As she briskly walked through the halls of the school from her portkey arrival sight, she noted an odd tension running through the students.  It wasn’t in the same way the war caused tension, this was lighter and yet simultaneously just as serious.  Girls and boys alike were crowded around papers, giggling and then saying words like "betrayal."  For the first time all year she heard the word "mudblood" from a group of young Slytherins.  She called them on it with a severe glare and subtracted fifty points.  They might not know her, given her only class being the oldest students, but she knew them.  Not by name, of course, however their faces carried similarities to children Athena had once known.
