In bed with adoption officer McMartin, Walden realizes she's a loon and ponders breaking up. Hearing that Alan turned down moving int a new home with Lyndsey to stay in the beach-house, Walden concludes they're wasting their best opportunities and risks telling the truth, as previous disastrous revelations didn't actually mes up the adoption. That works out for both of the men, or at least initially.
