Something I noticed and a little theory of mine concerning last night's E4 episode.....

Spoiler:

Mercedes looked devastated when she read the results, so I thought straight away, oh Carl's the dad, but then it turned out to be Riley so I thought she was just in total shock........but then the cogs began to turn. Carl took the letter from her, read it and said "Congratulations" to Riley, but Riley didn't read it I don't think (?) So could Carl really be the father and Mercy quickly realised what he was doing by congratulating Riley and went along with it?

thoughts?
