'Sampaguita Girl' is actually a real student and 18yrs old pa

Thoughts on this? Initially akala ko din na yung babae ay di tlaga estudyante and nagpapanggap na bata pa, pero still, shouldn't see also be held accountable dahil over 18 na siya? Alsoo, it means na may comprehension and ability siya to fully understand na pinapaalis ni kuya guard siya don, so bakit di nlang niya ginawa yun?
