A/N: This twists the option a bit, but I'm sure we'll be fine
Liara T'soni often felt like she wasn't great at adapting. While intelligent (and honestly, more knowledgeable than many Asari Matrons) at the end of the day, her lack of experience left her nervous about setting out on her own. For example: by trying to keep the Geth from killing her, the one of the universe's leading experts on the ancient civilization managed to seal herself in a Prothean stasis chamber.
For the first week, Liara was convinced that she only managed to prolong the inevitable. She couldn't move, she couldn't eat, she could do nothing but watch as the Geth and their Krogan master paced about, like a pack of predators waiting for their prey to sleep. She was helpless, and everyone there knew it; all Liara could do was hope they would find their way in before she starved.
But, somehow, neither came to pass. Days passed. Then weeks. She never hungered, never felt thirst, hell, she never even felt tired. For an expert on the race, Liara completely underestimated the Protheans. Their stasis chamber seemed like it could've housed her until the next supernova.
That said, Liara wanted to leave well before then. Her time in the chamber was already weighing on her mind and body. Despite floating in anti-grav, she felt heavy. Her limbs felt... cumbersome. Her body felt dense, despite being lighter than ever. It would've been a fascinating study, if she weren't mid-peril.
The longer it went, the more nervous she felt. Until one day, when she heard a conversation without the guttural undertones of a krogan. and the elevator above her move for the first time in weeks.
"Uh... hello? Could somebody help me? ...Please?"

Liara's soon-to-be rescuers were staring blankly for a concerningly long time.
"Can you hear me out there?" the asari maiden called, "I am trapped, I need help!"
Eleanor Shepard had a certain expectation when she imagined meeting the daughter of Matriarch Benezia. She might've supported Saren, like her mother, or she might've been an ignorant civilian, but at the very least, she wasn't expecting her to look any different than any of the other asari she'd met during her travels throughout the galaxy.
"I... L-Liara T'soni...?"
Shepard didn't even know asari could get that fat. The fact that at least two aliens seemed just as shocked as she did led her to believe that it wasn't an ignorant assumption on the token human's part.
"Thank the Goddess! I did not think anyone would come looking for me."
The asari floating in stasis looked like she outweighed a squad of commandos. Her apple-shape was more of a blueberry, round to say the least, with huge, pillowy thighs, and a vast expanse of stomach that would have likely hidden them from view without the effects of anti-gravity. Her breasts were blobs of blubber the size of her head, kept preternaturally round by the stasis chamber. Her arms were stuck in a t-pose, giving ample opportunity to observe how fat they were; each looked like a tube of blue dough in an overfilled pastry bag. Her fingers were chubby too, and a roll of flesh was emerging by her wrist.
"Listen, this thing I am in is a Prothean security device," the obese asari explained, "I cannot... move, so I... I-I'm sorry. Why are you staring at me?"
Shepard cleared her throat, using all of her military discipline to keep from rubbing her neck, like an awkward schoolgirl, "Sorry. I've never been to asari space. Most of the ones I've met are... less built."
"Well done, Commander," the turian next to her snarked, "Verrry smooth."
"I've actually seen bigger," a battle-scarred Krogan said in a rumbling drawl, "But, they were part of a cult. You in a cult, doctor?"
"...A... cul- no!" Liara goggled, hoping to the Goddess that her potential rescuers weren't insane, "By the moons of Thessia, what are you talking about??"
Shepard blinked, slowly realizing that the ragged bits of clothing that clung to her weren't part of an asari fashion statement. "Dr. T'soni... when's the last time you looked down?"
