Akane needs to help sort this out. Tomo needs to not do anything crazy.
But Akane needs a bit to sort out her feelings. We can't just tell her that she's a lesbian and make it so.
[] Send Kyoko to watch Tomo, make sure she doesn't stumble into a Barrier, or off a cliff. She needs space though, so no Kyoplomancy.
[] Heal Akane, give knowing smirk. Let her talk, rant a bit, ask leading questions. She needs to process what just happened.
This should take roughly one update. Then we can send her off after Tomo, and we'll know where she is. Seems explicit enough to cover all bases.
Edit: Better idea has been found.
