"Speaking of which, Donovan, I heard you two found this house and sorted out lunch in less than an hour this morning. Did you have some sort of miraculous encounter on your way here?"
Milton Lambert's words were a bit ambiguous. Someone with a bit of an imagination could easily interpret it as him implying there was something fishy about them finding the house so quickly.
Hector Donovan had spent some time with him and had a decent understanding of his personality, so he was sure there was no malicious intent.
He'd likely misunderstood, thinking Hector had brought his sister along hoping she'd get into the entertainment industry, and was deliberately looking for an excuse to bring her up and get her some screen time.
