"You could just leave me here," Harry put in hopefully (he'd be able to watch what he wanted on television for a change and maybe even have a go on Dudley's computer). Aunt Petunia looked as though she'd just swallowed a lemon. "And come back and find the house in ruins?" she snarled. (Harry Potter and the Sorcerer's Stone)
Is the ‘come back and find the house in ruins’ an imperative sentence, or is ‘you could’ omitted before come back?
