Araceli will be siding with Leliana, partly because she's one of her bards-in-training, partly because she is absolutely not in favour of being watched like she's a criminal. Equally though she'll have concerns regarding Galadriel (despite not being in favour of actually provoking them because the actions of one rifter, in her mind and as evidenced, can reflect on every single one of them) but more about her being treated fairly, being allowed to receive visitors, legal standing etc.

Whatever help Leliana needs, Araceli will offer.

And I'm pretty sure you know my Morrigan stance. You know smirking and snarling alongside Leliana she's got your back.
