I think if our tadpoles are meant to be different, they should put a short scene into the game which triggers the first time a party member dies.
Just a few lines making note of the fact that the tadpole doesn't leave the body. And then depending on whether this happens before or after meeting Edowin, some reactivity comparing the two different tadpoles in both scenes (whichever come second).
I have a sneaking suspicion that this is an intentional plot device - and that any Origin characters we kill or abandon in Act 1 will be coming back to haunt us later in the game.
