Funny you posted that. I may be willing to accept Selina being bi-curious and having such a relationship with Jen but even then, as GenAntiles posted, I've also seen women being chummy that way (and the only thing we saw onscreen was Jen hugging Selina, nothing else) while still being totally hetero. The butch, rough attitude may not mean anything other than an outward expression of the bitterness of her character. Maybe there's something sexual going on with Jen, or maybe there's nothing more than a deep friendship where such a display of affection means nothing other than that, one friend hugging another. But calling her out LESBIAN based on circumstancial evidence seems a bit much.
