Tom Quinn, a royal author, revealed details about Kate and William's relationship.

The pair fights frequently and hurls objects at one another.

When William is annoyed with Kate, he refers to her as "darling."

Kate is frequently portrayed as the cool one, whereas William is fiery.

Palace aides exacerbate the couple's anxiety.

Quinn likens their situation to one from a Jane Austen novel.

It is appropriate to respect the couple's private times.

Kate is a people-pleaser, and William gives in because he has been hurt in the past.

They, like all couples, have disagreements but eventually reconcile.
