Hi, I don't understand how deleting the email from sern's database will affect the past? I understand that the world line is changed by manipulating the actions of individuals in the past throught the use of D-mails which are also sent to the pass, thus changing the future/world line. So what exactly changed in the past when the data of the first D-mail is deleted PRESENTLY in this episode?
