She never saw them. By the time Olga arrived on the scene of Mandark's suicide, Megas, Dexter, and the PPG were already gone. Any fires were extinguished, and a majority of the smoke has dissipated.
Now I will give to that we don't know if she saw them before, or while she was going to Mandark's compound. Possibly to investigate the explosion, or she was going to see her brother.
Stufflikehearts - He is a Sith Lord. I love Blood Lord :3
Jeffffey - Blood, you look at the information someone says, look over what really happened, and reply in a way that makes them realize what they were really thinking.
Light10s - Blood Lord! Your avatars are becoming more epic. You make me feel like getting on all fours and submitting my loyalty and obedience to you.
Fievel - Numerous campaigns and conquests, countless bodies decaying after the abandonment of victorious battlefields. Such is the life of Blood Lord.
Dusk_Imp - Blood Lord is like a celebrity here. Everything he does is pure awesome. ALL HAIL BLOOD LORD
Doctress Who - Why couldn't there be a Blood Lord in every forum? It would make life so much easier.
