The guards flanking Sen murmur something in her ear about, "Not using your powers on anyone while we're gone," Then quickly move over to the two individuals who were staring at or greeting Sen. 
     The first heads over to the bar, and gives a curt nod to John, "Evening, I'm going to need one or two things. It's of vital, perhaps world-changing importance that you do [i]not[/i] give that child any alcohol, or for that matter too much sugar. Don't refuse her order, just give her a virgin drink. And don't tell her I told you this." With those hasty instructions gone, he moves off without even properly introducing himself. 
     As for the other, he approaches Cledwyn with zero acknowledgment of his, shall we say, eccentric biology, and gruffly says, "Could you please refrain from staring at our most holy lord and savior, Sen the infallibly omnipotent? I typically wouldn't mind, but we hold exclusive rights to her image so you really ought to convert if you're going to ogle at her." And with that, he hands the man a pamphlet about the "WONDERS OF PERFECTISM: THE RELIGION OF TOMORROW!" And returns to the child. 
     As for Sen, she's nowehere near as gruff and professional as her guards (or half as professional as they'd prefer her to be). No, she just stares up at the view of the universe ending for a while, until the batman greets her, at which point she gives a friendly wave and says, "Hi! Do you run this place? It's so cool! Can I please have something to eat? I don't really care what it is, I just wanna try what you make best!" By the time she's finished this message, her guard has walked over to clarify what's off the table. She doesn't even remotely notice the fellow staring at her, and after staring at the spectacle for a moment more, she happily hops into a chair next to the bar and waits for her meal.
