She needs to take her cranky pants off, lol. I'm sure Ian will jest about that as well, especially if she's cantankerous around him. Ian can easily be adaptable in their situation, so I'm open to the idea of Juno being confrontational and bitchy with him. But I should warn you, Ian isn't a pushover. I also think by Ian standing up and challenging her, it might earn her respect. Plus, if and when she warms up to him, he'll see a starkly different side to her, which would earn her some serious brownie points.
