Hello, freedom & truth lady, you have a vampire on your side. He's going to put some effort into being ostensibly supportive of Galadriel, partly because he really wants to study the Rifts and find a way back home. However, he's irritated at both Galadriel and Cassandra because they both seem accountable for this spectacular inconvenience. And also because chances are exponentially higher now he'll get found out as a vampire, which he suspects neither of the other women will be in favor of.

But it's fine. Let's go with club freedom and independence, and mostly do our own thang. He will offer discreetly to help, though, or at least be interested in Leliana's opinion on what can be done for Galadriel.
