Thanks to Matt for the following.
Every tuesday i buy the television magazine called whats on tv, today i bought the new one and it shows the tv listings for the week starting saturday 17th april and i had a look at the sky1 listing for friday 23rd april looked down to see the lost summary and found some rather good spoilers for episode 6.13 (well they were spoilers for me anyway). also 1 week ago i bought the tv mag and looked to see what it said for 6.12 and had some rather good spoilers (at the time), it mentioned michael and libby which was pretty good spoilers for me, 1 week ago. ive attached the scans to this email :)
