If the Yeoman looks distracted, it is because she is. The entire time, she's been on the com handling last-minute details using her very tiny headset.

For example, one private called to say, "I'm sick. Do I have to be in formation? Wouldn't it look bad for a sick crew member to be on live broadcast?"
To which the Yeoman cooed,
"Sorry to hear you're not well. But yes, you must be in formation. Unless you have a disability waiver from medical staff saying you are unable to stand on your feet. Please hold..."
Or the one where a specialist called saying, "Um... The shipment of extra toilet paper never got delivered. Please tell the Captain we'll need to delay launch or we're going to have a very unpleasant maiden voyage."
To which the Yeoman whispered,
"Oh dear. It was showing as delivered on my spreadsheet. Um... Try looking in the box labeled, 'paper products.' Bay 7, Row 2. If it's not there... I'm sorry to say, but we can't delay the voyage for inventory considered, 'non-essential.'"
"Private? Thank you for holding. Do your best to look good for the people you love. If medical can't give you something to hold you over, call me and I'll dig something up for you."
...and so on. Of course, whenever the Captain is about to speak, she puts her duties aside to pay careful attention. Today, every word coming out of his mouth is making her smile. The way she looks up to him is almost childishly obvious.
To his invitation she gives a salute and answers in a soft, broken voice,
"Ye- Yessir!"
