5. Breaking The Habit - S4 Olivia/Lincoln & Lincoln/Alt!Olivia - "Sugar" by Garbage
There are moments between them that he fills with meanings they don't share anymore – awkward pauses that aren't the shy seconds they used to have. He looks at her and sees who she isn't staring back at him, in how her expression shows she knows she's missing something. Her memories have slipped away and he's let them because it's what she wanted, but he can't rewrite who he is, and his feelings, like she did.
When he sees the other her, it's easier to remember from the red hair that they're not the same. Liv is warm and exudes energy, a will to be. He can't imagine her making the same choice as Olivia and she hasn't lost the mystery of getting to know him. He hadn't been sure she wouldn't just see a less spectacular version of her partner, but she does treat him as his own person.
The woman he felt something for doesn't exist anymore but this version of Olivia Dunham looks at him directly, speaks to him directly and sees him in the way he thought he'd lost when Olivia had become closed off. They're not the same woman and as he feels himself blush under her gaze at a quip about not bringing any coffee over, Lincoln's pretty sure that's a good thing.
