Athena just shows off.
And and is the snoopiest of all. >.<
Yeah because it was just three of us online. 
Hey, you. What Greek Mythology have you been reading ? This is my specialty.
Without Athena's help Perseus would NEVER have slain Medusa, okay ? If she hadnt given him Pegasus he wouldnt have killed the Chimera either.
Hercules wouldnt have been able to skin the Nymean Lion without her - EVERYONE came to Athena for advise.

Hollywood tends to modify everything A LOT !!!
