Ruby is working on tracking Lilith down and has arranged for Sam and Dean to meet up with her to follow through on some leads; they are traveling to get to their meeting spot when Castiel and Uriel kidnap Dean to interrogate Alastair for them. Alastair reveals that the reason Lilith had wanted Dean in Hell in the first place was so that he could break the first of The 66 Seals by torturing other souls. Alastair also reveals that Lilith is not behind the angel murders; if she were able to kill angels, she would've killed a thousand instead of just seven.
