Why Even Take A Paternity Test?!

One of the most scandalous stories on this début season of ABC's Mistresses -- other than all the mistresses (just kidding, there's only one mistress and the guy she was sleeping with died in the pilot) -- has been the fallout from Savannah (Alyssa Milano) and Dom (Jason George) sleeping together one time and the pregnancy that followed. This is complicated for a bunch of reasons: Savannah's husband Harry (Brett Tucker) had been pronounced pretty much sterile in the series premiere; also, Harry is white and Dom is black, so even if Savannah had kept the infidelity to herself and faked that it was definitely Harry's baby all along, that lie (if indeed it was a lie) would probably be exposed upon the baby's birth.

Anyway: Savi came clean with Harry about everything, including the fetus's dubious paternity, and though he tried to pretend he was fine with everything, in the latest episode he tells her that he won't raise a baby another man fathered and that she has to decide whether she wants to have the baby, or stay married to him. I mean, yeah, on the one hand, not cool; on the other, she did cheat on him, so she doesn't really have a right to question any of the conditions he places on their marriage. But she takes him at his word and tells him she's choosing the baby and he can go lose his own money on his restaurant from now on (I'm paraphrasing).

All of this happens with Savi and Harry and Dom ignorant of the baby's biological provenance; not only the marriage but also Dom's potential involvement in the child's life, if he did father it, hinge on the results of a paternity test Savi has ordered. (She's tried to get him to sign away his rights, but he wants to know whether he's the biological father before he does anything, reasonably enough.) So when she comes into her office and sees the envelope from the lab on her desk, it's a fraught moment.

Just as she's about to open it, Savi glances up to see Dom in an adjacent conference room...

...and then at a photo of herself and Harry in Happier Days...

...and bitch decides to put the envelope away unopened!

OH REALLY NOW THAT'S TOO MUCH.

Guys. I am not stupid. I know how TV works. I understand why, for the purposes of future plot developments, the writers of Mistresses wouldn't want this question answered definitively at this juncture, so that they have all their options open later. But couldn't they have accomplished the same thing by delaying Savi's receipt of the DNA results? (Has prenatal DNA testing really become so commonplace that everyone in the audience would know how long it takes to get the lab results back? I really hope it hasn't.) Would anyone in Savi's position really prefer to remain ignorant? Even if the answer is that, as a lawyer, she'd rather not know the results and be able to lie credibly to Dom about his relationship, or lack thereof, to the fetus, then as a lawyer she'd also know that when the truth comes out, those results will be dated and she won't be able to keep it up.

On the other hand, another plotline involves a perfectly normal-seeming suburban dad faking his own death and then un-faking it, so maybe this nonsense is the most believable story point in the episode.
