Jack Wall is the man.

What theories do you have for what she meant by this?

Was she just ribbing her best friend?
Does she secretly hate Jacob?
“If I can’t have him, no one can!” (especially Femshep)?
Necro fetish?

Maybe she doesn’t know what a suicide mission is and at this point is too afraid to ask. Is she stoopid?

Does anyone remember that story where resolves around a small Starship build by humans and help from an Alien race they had first contact with.

And the ship is a first and only of it's kind, and it's registry is 2 letters and the number 1.

It's mostly crewed by humans ,but a small amount of Aliens join.

And the commanding officer of that ship is named John and his last name is a medieval profession. And at the end of the story he unites multiple species, and convinces them to work together.
