Beside myself waiting for Tuesday!
Great thread - chuffed I have kept myself away from the spoilers one! So far...
Right, if you had an item with potentially important blood on it, wouldn't you store it a bit more carefully than just leave it kicking about a paper envelope? (This applies to Malik, Mark and Ziane). Odd how nobody has put this in so much as a plastic sandwich bag.
And what was Malik trying to ascertain with forensic tests? Without a sample of Ollie's blood (or a relatives) to compare it to, it couldn't be confirmed as much more than human blood?
Also, why did Ziane decide to give it to Malik for the 24 hours? Surely a quick glance in the envelope would tell Malik all he would need to know. Police would be doing the tests and have access to samples to compare it to (Emily's at least if not Tony's - like the different biological father angle)
