How would you get killed by the above poster? #2

Sparring accident.(tm)
Being so awestruck by seeing Tethenar's face if he were to remove his helmet.

That or a blade to the chest, which seems much more likely.
Proapbly crashed by his own Infernal after Lestathiel would secretly interfere with the summoning process.
Caught in Sigehr's erratic volley of felfire while charging at a band of ren'dorei heretics.
She'd end up as a victim of the said charge, being cut through with the sword the paladin is wielding. Due to the quick nature of the charge, she'd struggle to conjure a barrier strong enough in the given time, getting her head cut off in result.
A friendly joint portal study where attempted void/arcane fusion atomizes the test subject rather than sending it to the other side of the conveniently cleared lecture hall. It takes a couple of weeks to figure out exactly what happened with the awful reality of it hitting hard. Sometimes, scientific progress has a pricetag...
She'd surely stumble, swear a bit and by that would activate her staff which would shoot me accidentaly.
Probably in an some sort of entertainment establishment. He’ll be looking for company and Abysmia would be there masquerading.
He’ll hope to feast on her life essence but the only thing he’ll taste would be her blades. He’ll try to run, shift into a cat to escape but she will be relentless, wherever he will turn it’ll seem that she is there.
He’ll turn on her shifting to a giant bear and swipe at her, left, right... but she is just too quick! Argh!!! He’ll roar and shift into a raven hoping for a desperate retreat. At that point she will release her demon within and burn him a split second before he could get away, and only ashes will remain. Fel tinged ashes.
He would turn into fly form, peck my eyes out, then he will turn into cat form, scratching me from top to bottom, he would then turn into bear form, and he would just jump on me as I would vomit blood in a gore-fest. Then, he would draw out his Scythe of Elune, turn me into a worgen, and leave me as a mentally scarred, retarded, piece of a Death Knight loser :)
I'm gonna go with a classic.
She'd kill her in her sleep.
Mercy kill.

I can no longer control my inner demon, it almost completely took over. By using the last bit of energy left in me to keep the demon under control, I drop my warglaives, fall on my knees and ask the fellow demon huntress to finish me off. Fully understanding the situation I'm in, she asks no questions and does what is needed to be done.
Friendly fire in the heat of a battle. May or may not be due to eye beams.

That's all I got. I don't see these two butting heads at all :(

Edit: NINJAS!

Thuldrell would be defending people from Savoren's rampage. Sadly though he would be one of the victims. Atleast he died with honor.
Probably be caught sacrificing some peon and get stabbed when she resisted arrest.
While calling rain on the barrens after days of heat wave, accidentally strikes me with a huge massive thunderbolt that falls right upon me and burns my body to a crisp. Not a dust left for my funerals.

EDIT : Gross... can't believe I came up with such an atrocity.
Being polymorphed by him just as a hungry bear passed by.
Getting stabbed by her after she yanked my (precious) beard.
Thuldrell would touch Munkosh's beard (mostly) by accident.

They still haven't found every piece of the Nightborne's body since the incident...
Stun locked to death.
Enslaved and then sacrificed by Malaficus.
Laurenn ending up contacting large amounts of felfire, possibly getting burnt alive. Poor Laurenn.
