Hearing promise of Alexander's reward both girls nodded happily with a smile, as he then politely asked them to excuse themselves, with this last piece, "Please keep everything you learned all to yourself. Thank you."
Although the first part of the sentence could really be said to be redundant.
No matter how big much of a blabbermouth these two were, they would not dare to utter a peep of this, knowing they could be silenced with simply a thought from Alexander.
But just as Alexander was about to go back to his dark thoughts about putting 'that swindler' through the rack and snapping her from limb to limb in the most cruel way possible, he suddenly felt a warm hug envelop him, quickly followed by Gelene's silky whisper,
"Now, now, master there is no need for you to get so worked up. These girls need not leave immediately do they?" as the black lady then landed a light kiss on his cheek, letting Alexander smell the rosy perfume she was wearing.
