I mean, I’d LOVE if she did, and I feel like if they were real people, she absolutely would, April shared all that and she was still super mad at Sterling, Sterling’s actually mostly fine with her. But I’m not sure they’ll write it that way. TV seasons are built as these interweaving arcs, right, everything has to work together, like their arc had to build and really take off in the last few eps, after the break up with Luke, it had to be the reason why Sterling would get distracted enough from Blair to cause a rift, the breakup would need to happen in ep 10 along with the information about April’s dad getting out and add to the whole list of things Sterling was going through in the finale, plot developments can’t just be natural and organic, they have to feed into and be fed by each other.
So next season, it’s not just, she gets home and calls up April, we might not even get April or school at all in the first eps, there’s gonna be so much fallout and only then–well, unless John Stevens starts his plan to get revenge on them, then there’s gonna be a reason for their arcs to combine again. Most likely April will find out in some much more dramatic way, possibly not even from Sterling but Blair. Really depends on how they structure the season.
