In a fanfic scenario, perhaps she's tied up as part of a trap set by a powerful enemy within SHIELD itself. This could lead to a story of betrayal and her having to figure out who she can trust while in this vulnerable state. It could also show her using her wits to escape even while bound.
Well, it could be that Quake is tied up by some alien race that has invaded Earth. They've captured her because they sense her powerful abilities and want to study her. This would lead to a story where she has to find a way to break free and fight back against these invaders.

In a fanfic, the Agents of Shield could potentially discover Thanos' plan early. They have a lot of intelligence - gathering resources.

Well, a simple plot could be that a mermaid is accidentally caught in a portal created by some alien tech that the Agents of Shield are studying.

The agents would then have to protect her while also trying to figure out how to use her abilities to their advantage.
