My thoughts on the ILYs.
The first one - genuine but forced. You could see by his face he didn't want to say it, but had to stop Aaron walking away.
The second one - totally heartfelt and full of emotion. When he was facing Aaron and making eye contact, it was already out there, he just had to hammer the point home. When he said Aaron could tell Chas and Andy what had actually happened to end his suffering, that seemed genuine to me, as in their next scene he was completely convinced that Aaron would have done it. He put his life on the line yet again, risked everything to help Aaron.
The third one - completely genuine and again, plenty of eye contact. Of course they then had to ruin the moment by throwing in the "you know everything" line, but it keeps the ambiguity and as someone else has said, he may not even see that as a lie. I reckon it's something he intends taking with him to the grave, as there is no need for anyone to know the exact circumstances. As he keeps saying to Aaron, it would serve no purpose.
All in all I thought Thursday and Friday were amazing, and I will be re-watching again and again.
