The word is [i]relief[/i] - Lucien's feeling sentimental. 

'Follow my lead' means 'I have worked out you are useful, but inferior'. It means Surma probably hopes that Lucien is going to get himself killed doing something relevant, and her problem will fix itself thereby. He won't, but as long as she thinks that, she's an unquestioned ally. 

And evil [i]twin[/i] means [i]this is not Jackdaw[/i]. This is ᴇᴠɪʟ ᴊᴀᴄᴋᴅᴀᴡ, which makes this so much simpler. 

Still, she's Ailee's +1, those two can do a couple's waltz. Lucien's got to be the gentleman and dance with the one who brought him. 

The bolas are in the air. Lucien's still touching the Professor's shoulders gingerly - first to help position him between himself and Surma, now so he can make a friendly shoulder squeeze, ground him in the moment. 

"Hey, Professor, we've got plenty of clowns in the circus right now if we need one," Lucien is the angel on his shoulder, reason to madness, "but not many brilliant academics. I need you to tell me everything you know about what that ᴊᴀᴄᴋᴅᴀᴡ is, and keep talking. You said you could be a repository of knowledge here, right? [i]Prove it.[/i]"

The information he gets out the Professor might be useful, it might not be. What's important is that he's now put the Professor's pride in the way of the Clown Madness. Pride enough to rival Ailee's.

[Talk Sense - Appeal to emotion, Wisdom, 5, 2, +2 = 9 - he does as I ask, but I owe him.]
