Here's a thing that pops up on other threads, PA is not "allowed" to be in HP's life.
Some feel he wasn't allowed to adopt him - because HP's birth Dad wasn't actually out of his life as suggested in the press, but was in fact paying towards his care and there are photo's of his Birth Dad with him for a few of HP's early years.
It was suggested that PA upset/offended birth dad (and there is an interview with both PA and Birth Dad giving their differing views on that situati
Then you have fact that PA's 2nd wife E was around for a bit longer than sometimes folk realise. I watched his shows (the ones after KP and him had split). You can see E in the background of one of the xmas meal video's in PA's first house after the split.
I noticed an odd thing, there was an episode of PA/KP towards the end, they were in the USA and had a photo shoot, wearing denims (HP, Jnr and Pcess) and PA had a photo on a canvas on his kitchen wall after the split showing him holding all three children's hands taken from behind them so you could only see them walking away, not their faces. (cute pic)
As time went on, each episode, it changed and HP's head was blurred out
Eventually it only showed PA and Jnr and Pcess in it.
Now they did state that KP felt PA needed certain trained Nanny's to be able to have him in his care, and indeed PA mentions this fact in his show. Also he then stated that he'd got the required care team and HP resumed (after a gap) visiting him along with J and P.
Then E joined PA and he began travelling more with his career and you could see J and P being left at the airport with Nanny's heading back to KP's home.
So I got to wondering if it was easier to distance out from HP for PA at this point? It would have looked bad for PA to have simply dropped HP having had a mahooosive money making hit with Unconditional and he was using the split to re-establish himself and keep his Star moving upwards.
