I guess this is kind of a mother's day post even though it's not necessarily exemplifying Mother's Day. Micah is a mom, single, and doing her best.
While not a canon scene (maybe "yet" it depends), I imagine this as an extension of how she is looking to get back into the dating scene. Momma B. would most likely be encouraging her to wear a more revealing bikini than she's used to, and maybe inviting her to a lake trip to boost confidence where she feels more comfortable and there are less people around.
Or perhaps it's a scene from the past, at the lake her father frequents, and where she took the picture of her son proudly holding his first big catch with his grandpa (who did most of the reeling-in) beside him.
Either way, it's surprising where things can wind up in just a few short years; for better, or worse.
