Heh, Cassandra's probably pulling a 'disgusted noise' face when she sees the stoned looking bunch that is her Inquisition. 
There's still some lingering dislike between Leliana and Morrigan though, even if we did find out Leliana cares about her a bit. :S
"Morrigan looks pleased with herself...that smug face..."
I picture Leliana rolling her eyes when she says that. I think their relationship has progressed to the point where their dislike has become 'annoyed tolerance'. They've been through enough together that they respect each other, but their personalities just don't gel. Respect without affection, or something like that.
There is a bit of messenger tag between them.
Leliana: What did Morrigan say?
Messenger: She scowled and admitted that Kieran chose the gown.
Leliana: I knew it! Red velvet... the boy has wonderful taste!
Messenger: Oh! She also said to tell you to stay away from him. You are... a bad influence.
