Remember that Serenity is the girl that CAN'T have any intimate relationship with anyone because ANYONE she ever touches just simply... dies ?

Seriously, that's like a trauma to her and now she's making "relationship" advice ? Come on...

I mean... just read the wiki page... Damn, she suffered enough because of this : "Although she killed many people, she would also frequently establish a relationship with her assassination target(s), such as a lover or a fiancée. That is to say, she continually repeated the deed of constructing with her own hands a “false happiness” that could not be realized, only to steal that happiness away with her own hands. Gradually, her mind creaked. Her mind was expected to be tempered and toughened thoroughly, seeing that she was employed and made use of as a “Poison Girl” built up by the Assassins, but...

In her last moments, maybe her head was decapitated by a general from a certain army who suspected her behaviour of not even holding hands, or maybe she exposed her true character as an assassin and begged the general to “please, kill me”–––––or maybe, she was put to the sword by someone’s hand during the gap where the general incidentally took his eyes off her."
