Oh hi hi anon, sorry for the lateness of this response~
I actually think June was a great character as far as being an actual character goes, with purpose and personality and not…like, y’know, just one of those rando guest stars that pop in and out for their name recognition and to waste time and space that could be better used elsewhere. I like her more than I like Holly, April, and even Jan from last year, just for instance. And yeah I think it was way past time for someone to be enamored of Blaine’s talent and to push him in the direction of…well, really going for this thing that he’s passionate about, no holds barred.
But June also says and does several things that I find pretty inappropriate for her relationship with Blaine. Like…she’s his benefactor and patron and even mentor in a way, but she’s not his friend, so it’s not her place in the least to involve herself in his personal life. And the way that she’s rude to Kurt and discards him so easily (at first) gives me the impression that she only cares about people as far as they can be of use to her, which is not real caring at all. She admires Blaine, but she doesn’t admire Blaine if you know what I mean, and either way it’s not an unconditional admiration. If he doesn’t present himself to her liking and utilization I don’t think she’d hesitate to discard him as well.
Which is her right, obviously; June’s the one who’s quite literally giving Blaine things for free, for no other reason than the fact that she believes in him, and is certainly under no obligation to coddle him about it. But we shouldn’t, y’know, overestimate her affection for Blaine just because she likes the way he sings and projects her own life onto him. “Finally someone likes Blaine and his helping him succeed!!” well, yeah, but it came with fine print. June’s not Blaine’s Fairy Godmother, she’s his Crossroads Demon.
The nice thing is that some of her perspective does change by the end of the season because Kurt and Blaine are magic and change her views with the power of music and so forth XD. I think Blaine might be a good influence on her, and actually she might legitimately be a good influence on him in many ways as well. And, let me be clear on this, I don’t hold her the least bit culpable for the problems Kurt and Blaine went through; that’s all on them, and then pretty much most of it on Blaine.
Basically, I often tag my June posts with commentary like “June’s not here to be liked,” which works in several ways. Obviously June doesn’t give a poop if people don’t like her because she likes herself too much to care about that. Secondly, June was written to be an obstacle just as much as she was written to be a benefactor. We’re not meant to, like, root for her and her opinions or something, we’re meant to root for Blaine has he circumnavigates their relationship.
