Were there no other solution?

In this Moment when Hughes was so close to find out the truth he wasn´t alone....
Amy standet in thi Libary and try´d to rescue his Life.
Amy: "It´s so late, dont you think? Go Home to youre Family"
Hughes: "No Way, i have to do... you dont have to stay here. Go Home and sleep"^^ He was so nice as ever to her, she cant stand the feeling, to lose him. But as she look´d to the left, dhe know´d that she can do nothing for hi anymore. Lust giv´d her a sign to go....
Amy: "Maybe your right. Good Night."^^ Hughes: "Yeah, see you tomorrow."
(That hurt´s!)
After Envy shoot Hughes Amy ask´d him: "Where there no other Option?"
Envy: "Ts, why so emotionall tonight? XD And i thought, you where reasonable!"

Maybe she giv´d up her Life, it doesnt say, that she is cold as Ice...
