She has to

Knowing that she was now holding everyone up, Leliana reached behind her back and unclasped her bra and quickly threw it onto the altar along with everyone else's clothing. Unlike Alistair she chose not to cover herself and instead to stand tall to preserve as much dignity as she could in these circumstances and bared her modest breasts to her companions. Her pride soon faded as she realised that she had more to remove and she slowly bent over and slid her smallclothes down her legs and stepped out of it.

Once they were down, she took another moment to see her friends' reactions; Morrigan seemed indifferent and barely gave her a second look, she was still likely annoyed at the whole situation while Alistair caught himself staring at her for a lot longer than he should have been. Leliana had to remind herself that this was the first time he had seen naked women and there were three of them at the same time. The biggest surprise, however, had to be Elissa who didn't even hide her drawn out stare at all of Leliana's womanly features. Leliana had long been attracted to their leader but had never acted on it as she wasn't sure whether or not she was interested in women, if the expressions were of any indication, she most certainly was.

Rather than throw the garment onto the altar, Leliana decided instead to bend down from the waist and pick it up off the ground before slowly walking over to it and placing it down. All without breaking eye contact with Elissa, who only gave her a small smirk in return. She then turned back around to face the flames as well as give Leliana a full viewing of her ass which she took full advantage of now that she couldn't see her.

"Now what?" Alistair asked awkwardly still covering himself as best he could with his hands.

"I guess we just walk through" Elissa said matter of fact as if they weren't talking about walking through fire. She then turned around to look at Leliana and grinned. "Hey Leliana, you're a true believer, would you care to walk through with me?"
