Haelvia would have been lying to herself, if she said she wasn't tempted.
Due to the special status Lieutenant Teneca accorded her, she was treated with respect by everyone in the Highblade fortress. Some of their Officers and senior enlisted leaders even greeted her casually to engage in small talk.
Conversely, Haelvia had been in Guild Metal Wolf for a little over a year. To sum up her time with them in a single word... it was... lonely.
She had no friends. Her peers barely gave her an uncia of their free time. As for respect? She'd almost forgotten what having that was like.
If Haelvia surrendered to cowardice, the Centurion couldn't blame her.
Loki, after all, was the better pilot.
He gave in to his demons without anyone's say.
Coraline would probably have begged her not to go-- there was really no logical sense to it.
