So this is set on a busy planet, maybe Persephone, and the crew finished some business. Mal comes up to the bridge and tells Wash to take off.

Wash; Right, captain," but Wash looks at the controls confused.

Mal; Wash, take us up."

Wash; Right, up." he looks at the panels like he's never seen them before then sees the stick throttle, "Oh, a stick." grinning he grabs it then starts pressing buttons.

Zoe enters the bridges and Mal turns to her confused.

Mal; Is there something wrong with your husband?"

Curious asks "Why sir?"

As an answer he points to the pilot who's holding onto the controls grinning from ear to ear looking out at the docks. Concerned Zoe goes up to him.

Zoe; Honey, what are you doing?"

Wash; I'm flying, aren't I flying? Why aren't we moving?"

Mal; Because you didn't turn on the engines."

Now looking a little angry knowing Wash was probably on something.

Wash laughs and says "Oh right," scans the controls over and over. "I know it's one of these."

Mal; Wash what the hells wrong with you?"

Wash; Nothings wrong with me captain, you wanted off we're getting off." Finds the button with a little "Ah." and presses it. Engines come on.

Mal turns to Zoe and with little face signals wants to know what's wrong with him, Zoe is just as concerned and shrugs not knowing. So Mal goes up to Wash.

Mal; Wash..... Wash!"

Wash is still holding the stick but isn't moving it, his grin still plastered on his face. He turns to Mal.

Wash; Ya Mal?" replies with huge grin.

Mal; Did you take Drops?" Zoe cringes knowing the danger Drops are and hoping her husband hasn't found himself in that trap, yet worried from his current behavior it might be true, getting angry inside if he allowed himself to willingly try the stuff. Both are surprised by Wash's vehement answer.

Wash; C'mon Mal what do you take me for? You think I'd try that(chinese swear). I'm better than that. I've seen what Drops do to people. I'm much too happy a person to resort to phoney feelings
