Oh yeah not a problem. It's a complicated relationship.
She'll fight the same as she would for anyone in the Celestia Family, tooth and nail, till she's got nothing left to give, etc, cliches, etc. If you work/related to her, she'll generally defend you like her life depends on it. She's a good ally to have.
Also she trusts Avery to do the same, so I suppose they have a respect for one another. More like a mother/son relationship than a sister/brother the more I think about it XD
IF something were to happen on this mission, she would probably sacrifice everyone else for Avery though (no offense guys). Though she might try to save Heinrich as well since he's her apprentice XD
She doesn't like Dante so he's boned XD
But she also simultaneously wants to beat Avery lifeless by the way. That's the complication XD
