I was just trying to find mention of them here as I can't find them on any of the discs, and I thought they were included. I was sure I had read previously on the contents listing here that they were, but that doesn't appear to be here now. :(
Yes, some people mention the inclusion of webisodes, but I guess they just mean the Resistance and Razor webisodes.
I did read that there was some legal problem preventing the release of the Face of the Enemy webisodes from being released on DVD/BD. I hoped this was either incorrect or limited to the US releases of the collection.
If you actually own the Blu-rays and cannot find them anywhere, I guess they are really not included. :(
Sadly Andrew is correct. For licensing reasons The Face Of The Enemy has never been included on any release of BSG.
It's a shame as it makes for really interesting viewing and as a great character driven piece it gives real context to some of Lt. Gaeta's actions in the latter half of the final season. It also introduces a fantastic new Number 8 model who only appears in these webisodes.
Viewed together they make a nice intense addition to the stunning final season and whilst not essential to the overall storyline it's a real oversight that these were not edited together and included between the episodes "Sometimes a Great Notion" and "A Disquiet Follows My Soul".
I'm not sure if this can still be viewed online but it's definitely worth a look.
I believe there was some confusion as it was listed in some Region 2 releases as being a special feature but was never included.
