I too am one of those mutated hybrids who likes to get into their characters in WRPGs. Ergo, Erika found Miranda somewhat easy to get along with while Jack reminded her too much of how she was back on Earth before she joined the service: violent and vulgar, her only peaceful times being those when she licked yet another poor bastard's blood off her knuckles.
I thought it was kinda cute that there happened to be a picture of Liara by the ship display. How I imagine Erika staring longingly into that portrait, recalling quiet (and some not so quiet ;3 ) nights of bliss with her blue-skinned companion.
I admit, I actually felt the heartbreak a little when Liara refused to join Erika on her quest to stop the collectors. And try as she might, as many times as she visited in between doing random favors for the other squadmates, Liara was still wrapped up in her own quest to usurp the mantle of "Shadow Broker" (well, that's how it sounds; she could just be wanting to kill her/her/it/them and get them out the way of... something).
Erika tried to find solace in her other squadmates, but to no avail (though for achievement reasons, I actually disconnected myself from Erika for a bit and allowed her to completely jump Jacob after suffering a complete squick [http://tvtropes.org/pmwiki/pmwiki.php/Main/Squick] moment with Garrus {totally my own fault; personal curiosity got the better of me yet again}). I can only hope that Erika finds some type of resolution to this conflict, either with Liara or through some other means, lest the entire galaxy suffers a shattered jaw.

What were we talking about again?
