Rasa examines the dossiers. One immediately jumps out as the frontrunner, but he figures he'll give each some thought.
Athena certainly appealed to Rasa's desire to understand the likely legendary beast that felled his father, and forced evolution seemed like a potential shortcut to gain some power. But in the end, he wanted to earn his own strength and he knew he wouldn't have the patience to study myths.
