Okay, I think many people will agree that Daniel's past is the most complicating of all :(
So I am confused.... Did he work at Oxford Uni, and do them Time Travel tests on the rats, and then eventually his brain got fried and he lost his memory or something?? Then he got taken care of by a girl... What happened after that? Charles found him and sent him on a boat to the island, when he got the island he was cured...ish :)
So where and when did he make his girlfriend ill... OMG so confusing :(
Was it while he did the test on a rat? He did tests on Theresa???
