I actually came up with a thought too.<br/><br/>Maybe Latvia's healing can heal ALL types of injuries including fatal ones, whereas Liliana's can only heal UP to fatal injuries. In her bio it said she has trouble healing fatal injuries, so maybe she can't heal those but Latvia can? That might be fun because then the two could meet someday and perhaps hit it off together.<br/><br/>Also Latvia's healing is pretty instantaneous too. His regeneration is accelerated since it's a passive effect but when he heals others it's instantaneous, but then again it depends on the nature of the wound in question. He can instantly heal minor wounds and heal medium wounds within a matter of seconds. Fatal wounds take a little longer though, probably up to a minute for him to do.<br/><br/>Oh and I went back and looked over and you're right there's no stipulation on powers not allowed to be doubled.
