Ciel in Wonderland Part 2 was good took an unexpected turn and became serious. We realise that the OVA is set between series 1 and 2 and normal Sebastian sitting on a chair next to a bed where Ciel's limp body is lying, wearing the clothes he had at the very end of season 1. It's pretty clear that it's Ciel's soulless body and Sebastian was reading Alice In Wonderland to him.
