This is the song I'd choose for the Warden while desperately searching for a cure. It would be a dream sequence of how much the Hero fears for Leliana. Most would be mixed with scenes from Origin with fears of what's could be happening to Leliana in the Inquisition and the perils that could come from finding a cure.
Lost
(Within Temptation)
My hope is on fire
My dreams are for sale
I dance on a wire
I don't want to fail her
I walk against the stream
Far from what I believe in
I run towards the end
Trying not to give in
She's lost in the darkness
Fading away
I'm still around here
Screaming her name
She's haunting my dreamworld
Trying to survive
My heart is frozen
I'm losing my mind
Help me, I'm buried alive
Buried alive
I'm burning the bridges
And there's no return
I'm trying to reach her
I feel that she yearns
I walk against the stream
Far from what I believe in
I run towards the end
Trying not to give in
She's lost in the darkness
Fading away
I'm still around here
Screaming her name
She's haunting my dreamworld
Trying to survive
My heart is frozen
I'm losing my mind
Help me I'm buried alive
Buried alive
I tried to revive what's already drowned
They think I'm a fool
Can't realize,
Hope plays a wicked game with the mind
'Cause I thought I thought love would bind
I cannot revive what's already drowned
She won't come around
She's lost in the darkness fading away
I'm still around here screaming her name
She's haunting my dreamworld trying to survive
My heart is frozen I'm losing my mind
Help me I'm buried alive
Buried alive
