After her set with John, Zeta's out in front of the line and she's taking full advantage. She's juiced on adrenaline, the spotlight, and being back on stage and she kills her production numbers -- she hits every note and every spot perfectly.
She practically glows when she comes off the stage, pausing to blot her face with a towel before heading out front, still in costume. Hell, it's better than any of her dresses.
She nods to Mike and he draws a glass of water for her. She'll drink later but she's not stupid and she knows she sweated out a lot during the set. As unladylike as that might be to acknowledge.
She smiles at the person next to her at the bar and sips her water since they're watching.
