3. When you finally get the reveal, the result is amazingly, over-the-top gruesome. I can think of no reason the writers would want to do this but to create silly melodrama. Just the death of your mother would have been a blow enough for Hawke.
It's a mix of wanting to make an emotional beat for the player and wanting to continue to drive the dull nail of "MAGES ARE EVIL" into our skulls.
It couldn't be a serial killer (nor a detective storyline) it had to be an insane mage for no other reason than being insane.
5. It's especially odd, because Gamlen shows real sadness at his sister's death, which actually *did* get me choked up and empathizing with him more, but your responses back to him are still rather without effect, considering this was probably the worst day in your life.
Male Hawke has a cringe worthy delivery of "My mom died" to Aveline after the fact too. It's said with all the deep reservoirs of emotion that one must summon forth to announce they ate an alright burrito today.
3 - The gruesomeness was to illustrate the horrors of blood magic. Had Leandra's death seemed to be of natural causes, there would be no reason to associate the death with magic, or as caused by a mage. I think it was done this way to deliver more drama (not melodrama per se) - and to further give the player pause when considering how to act in other mage or templar-specific quests.
I get what you're saying but it was totally melodrama, especially since you can have last words with her and then angst over how it was your fault.
....which it really isn't any way you cut it.
I don't know how I'm expected to feel any kind of emotion over my momHawke dying if I barely even spoke to her throughout the game or spent any time with her whatsoever.
That's the problem with the Hawke Family. They're all doomed from the start and from the first death to the last they're all emotionless because you barely know the characters.
Had Merrill, Aveline, Varric, Isabela, or Fenris died instead of any of those characters I would have been emotional. Those characters have far more depth, better characterization, and you care more for them than any of the Hawke clan.
I guess a lesson to learn here is this:
For a character's death to matter that character needs to be a companion. That companion needs to be capable (who's going to mourn a companion who talks about how unsure they are or complains that they're just not strong enough constantly? Sure you could make it a pity death where the player feels sad but you're just as likely to have the player cheer when that character finally dies.)
That capable companion who's strong enough to have made it on their way without the PC is then killed off in a non-arbitrary way. That's another problem the Hawkes have. The Ogre just happens to kill which ever sibling that Hawke is the most alike in class...for no reason. The sibling just happens to be the only person of a 20+ group going down the Deep Roads to suffer from darkspawn blood. The mother character just happens to be a victim of a serial killer.
Not ever companion death must be from PC betrayal or heroic sacrifice, but heroic sacrifice works because it's emotional and meaningful. None of the Hawkes have meaningful in-character deaths. Unless you count the Ogre thing as "defending mother" in which case it needed to be handled better because it just looks like the Ogre targeted the sibling and one-punched the sibling out.
Once the character dies the reaction to that death is also key to hitting emotional responses. Look at the Buffy the Vampire Slayer episode 'The Body.' In that Joyce dies in the beginning and the whole episode deals with the characters reacting to the death, Anya's reaction being the most tearjerking one of the bunch.
The problem with the deaths of the Hawke family is that each one of them get maybe one reference after the fact and then it's forgotten. Their deaths mean so little in the long run and Hawke seems so completely emotionless to them.
The manner in which they die is also just PLOT HAMMER falls on their head instead of happening in an emotional or suspenseful manner. And the characters are forgotten as quickly as possible.
Although, Mom Hawke got more references than any other Hawke death. She's used as a weapon by Meredith to get you on her side.
