Oh, I wonder. Not in a way that anybody else could have made that connection, right, I don’t think April was THAT discombobulated and nobody else even mentioned it. But it is an interesting that April made such a point of it to say he brought up secrets nobody else knew, you’d assume maybe he hinted at it.
But still, I think that whole bit was mostly for comedic effect, and it would get pretty unfunny if he held outing her over her head. She’s never want Sterling to use her bombshell if it meant Craig could out her in return. I think she was just disturbed he knew so much and was paranoid that MAYBE he knew about her being gay and then decided he couldn’t and hence went ahead and gave Sterling the info.
