Sorry got distracted by Beowulf making it into the next round of Rosen Garten but it occurred to me that its been established that without a suit the deltans can't live on Earth so with that in mind it could be safe to say that the opposite is also true that without a suit... an earthling couldn't survive in Delta. However we have seen one exception to this rule Lord Hydra. It was a double fake out after she entered that basement lab in the office building and revealed herself that she normally wears a suit regardless which world she's in, she was able to function perfectly well outside of her suit on earth. So theoretically speaking Aurora just needs to give her researcher slave gal pal Lord Hydra's suit and she would be able to visit Delta without risking her life.... or they could take a suit from one of the other world commandos that invaded earth to get back at Delta.
