Ever since learning that his mother, Diana, had arrived in town, Leo has been in a panic on “Days of Our Lives.” Now, as he tries to make sure she doesn’t turn against him and ruin the life he has built for himself in town, the two will finally discuss the big secret they’re keeping on the Wednesday, Feb. 6 episode.

Diana (Judith Chapman) came to Salem after learning Leo (Greg Rikaart) was there but has so far refused to help Will (Chandler Massey) and Sonny (Freddie Smith) rid themselves of him for good. In addition, she has stunned John (Drake Hogestyn) with her arrival, because he didn’t know his ex was actually Leo’s mother when he tracked her down.

Leo has also confronted his mother about being in town and has been worried she would reveal something from his past that could potentially destroy him. Now, as he pays her another visit on the NBC soap, the two will discuss the big secret he is desperate to keep hidden, even though it could expose them and put them at risk of it being revealed.

Of course, that won’t be the only potential secret about Leo that could be revealed. When John discussed the situation with Marlena (Deidre Hall), she mused that Diana had given birth to Leo after she left Salem. Now, John will realize what that might mean since he had a past with Diana—and he will confide in Roman (Josh Charles) as he realizes a huge fear.

“John confides to Roman that Leo might be his son,” spoilers reveal.

As it turns out, Leo may not be the only one in Salem with a big secret after all.

“Days of Our Lives” airs weekdays on NBC.
