Well he really wanted to go with Tapu but then he realized that Tapu baba can't love anybody except herself and there is no point in taking Tapu with him
He still wants to take revange from Tapu for using him and he is going it this way.
lol he knew that already when he said hes taking her to mauritius! remember he ssaid...i dont care if u love me or hate me blah blah blah. he really is foul headed and sleazy just wanting money! then what was with all that stuff at the start about not wanting money?
