I really like Alexa, how can you not, she's a full fledged nice character
Drew though? most of his thoughts is about Alexa (cool he loves her but still, even Alexa thought of other stuff), he didn't even seem to be that interested in his job, nor really anything else, his care for Jack also feels very plot relevant not actual care
Carlos seems to be more of a friend to Alexa than Drew even though they barely know each other
