I’m always afraid–as I think most of us are–that if they give us a great character who’s a PoC (or LGBTQIA), they might snatch them away again at any moment, usually through some senseless death used to motivate/give “depth” to the white characters (yeah I’m pissed at you, Sleepy Hollow).
The Grimm Writers could definitely give Hank and Wu more screen time, character development, and storylines. But they’ve also built up a certain level of trust with the fans when it comes to not killing off everyone we love (just Kelly, ouch). I’m just hoping that what we’re getting here is more story for Wu and not a build-up to killing him. And I think it’s sad that one of these awesome characters getting screen time makes us all so nervous partly because it’s so statistically likely that if someone dies, it’ll be them.
