Ivanova is second in command on Babylon 5 and yet she is definitely number one when it comes to wit. She has a great way of putting someone down and always has a snappy answer, especially to stupid questions.

If you were in a pub with Ivanova you might be worried that she could drink more than you.   She would almost certainly be the centre of attention and her wit would upset some of your more boring friends.  She would probably be unaccompanied so all the blokes would try to chat her up.  They wouldn't succeed.

She is absolutely loyal to Sheridan and Babylon 5 - fanatically so.  She seems a little lonely sometimes and I can't help but feel a little sorry for her, she seems to have no soul mate. I suppose Marcus is the closest, though she almost certainly knows that he desperately wants the two of them to get together.

By the way, loads of Babylon 5 net-heads believe that Ivanova revealed in 'Ceremonies of light and dark' that she thought she loved Talia Winters. I'm sure she said that but we can't believe (much as we might like to fantasise about it) that Ivanova did not love Talia Winters in any way other than as a sister. It was very mischievous of JMS to throw that one in there. A bisexual Ivanova just doesn't sit right. I'm sure that the character has been crafted along the lines of a person searching for a meaning to life, a soul buddy, someone to cuddle up to and confide in. 

Ivanova has a mild telepathic ability. Her mothers was much stronger, she had to take drugs to suppress her ability which drove her to commit suicide. Ivanova has never forgiven the Psi Corps for this. Her brother Gayna was killed in the Earth Minbari war. Sheridan trusts her completely.

Towards the end of series four, Ivanova took command of the Army of Light against Clark while Sheridan was incarcerated.  She did a pretty good job, but suffered some fairly serious injuries in one of the final battles.  She was only given a few days to live but eventually recovered.  She also found out what feelings Marcus had for her.  Theirs is one of those frustrating relationships don't you think?
