Both Anakin and Poe asked Rey for at least one dance, and Poe probably asked for more if she looked like she had time for it. Kylo avoided Rey probably as much as she avoided him, unless it was to poke at her slightly for a response, cause he's an ass.
I feel like Kylo was probably there earlier than Eliot, but as soon as he could went and found Eliot and Petunia and hung out with the two of them basically because this whole thing is super uncomfortable.
