Am I one of the only people that actually liked Kaiden?
He was a little too bothered about rules and fraternisation regulatins, but we worked through that. The bit where he and my Shep got interrupted was... frustrating. Could have cheerfully socked Joker for that. He took a little bit of warming to, but I brought him with me a few times, and kept talking to him, and he grew on me. Then it was bye bye Ashley...
I like Liara, don't get me wrong. But personally, I found her romance a little too quick to get started. If that makes sense.
