In the mornings, Dirk flirts/talks with Cleo, because Shilpa keeps herself to herself in the mornings, behind the shades, washes etc, yet when Shilpa finally comes to life, Dirk turns his attention to her, while Cleo is sort of shoved out.
This is a love triangle without the sex and romance
Cleo fancies Dirk, who fancies Shilpa who doesn' fancy either of them.
