* Yugi's death is one of the saddest moment in the entire Arc 2 since it is very unexpected.
** Make it worse that Minato and Jiyuu are almost incapable of HANDLING it and they have to convince themselves he MIGHT be alright in the end!
* Minako's whole character fits here perfectly. She finds out her friends don't know who she is, and Junpei dies shortly after they remeet.
** Arc 3 ramps this up because she honestly believes that she has been left behind thanks to Divine.
* Zelda's death is quite sudden and unexpected compared to some of the other Dark Signer's. She has no chance to say anything, she just dies. Made worse that Flynn could not stop it.
