"Lysergic acid diethelyamide," Walter adds cheerfully as he deposits the tissue sample into a petri dish. "Wonderful stuff - useful for much more than you'd think."

He turns and starts for whatever lab equipment he requires, glancing over his shoulder at Olivia and Peter. His eyes flick pointedly to their linked hands, and he smiles faintly before adding, "Analysis will take time. Peter, Olivia, would you like a sandwich while we wait?"

Apparently Steve doesn't get food, or possibly doesn't exist unless he's being poked with sharp things.

Olivia bites her lip and disentangles her fingers from Peter's, though she's smiling as she does. "No, that's fine, Walter. They actually did feed me while I was on the other side, so I promise I'm not starving."
