Are you suggesting that Madeleine grazed her knee in the UK and then waited until she reached 5A to squash herself behind a sofa to bleed? That sounds likely (not).
I'm pretty sure you don't have any evidence that TS's grandfather lived in 5A.
I'm not an expert on the training and handling of those dogs, which is why, unlike some, I refrain from criticising the actions of those who are experts.
I am suggesting that Madeleines knee
1) may well have had to wait until arrival at 5A to be cleaned and dressed, or if she is anything like me
2) she would have picked the newly formed scab off. I always did and it bled. But we don't know.
The first thing that children would be likely to do after a quick look at all the rooms and a bounce on the beds is to look out of all the windows.
Btw, do you KNOW that the settee was pushed right back under the window when they arrived? No, you DONT
3) Additionally, we understand that one of the children had a nose bleed in 5A.
There are reports, which have been on here several times and you
must have seen that Tasmins grandparents lived in 5A. It is probably in Tasmins statement or the PJ statements; it is definitely in some of the videos that you have seen as well.
You
will have seen it and I am not falling for that deliberate timewaster again.
So three possible sources of blood, apart from previous tenants
