lol, they are 'hiding' because it makes such great ratings. Annoying as it is, this is the only way for the writers to stall their relationship and continue to dramatise their storyline. I would love for them to be public as a couple and proud of their relationship but the reality is once Charlie finds out about Brax's crimes their relationship will end. She'll still be in love with him, but they won't have the happy ever after that we're all hoping for. The season final is in 6 months and we will still be just as frustrated with brax and Charlie as we are now. Sorry for the pessimism but fed up getting so excited each episode and having nothing eventuate. Maybe I just need to detox for a while and come back to it? lol
