That would make sense-since it is so slow moving.On my end,I consider Pluto to be what you would call "closing chapters" or "new beginnings". As there is something "final" about the transit-especially when it changes signs.
Pluto in 8th is said to be "home" here and thus makes the generic Scorpio themes prevalent.
In the 8th, there are sudden shifts/up and downs. And at worst losses, but for some others gains.
Pluto in 8th could focus on digging or going underneath. Some internal investigation, follow through or finding the answer to internal questions asked that may not be available on Google.
One may come face to face with sexuality issues, mortality fears, possible despondency with regards to the future, questions of personal "purpose", an increased desire for more authentic emotional exchange, some "dark" thoughts on the possible liberating effect of suicide etc.
Wherever the attention goes to,there is an extended amount of energy and/or possible obsession with that sibject; turning it inside/out constantly until letting it go and not necessarily due to an infallible resolution.
Saturn moved to Scorpio in 8th by whole sign in 2012 and things got very deep for me.
It was as if the superficial "surface" living was not adequate. I had to feel the "purpose" of why i was doing what i was doing.
I was quite miserable.And life carried on as per usual but internally,i was cooking slowly- as the 8th is not where radical changes are initiated. But the Arc to the Mc ime.
Though it wasn't Pluto,Saturn in 8th gave me a taste of what the 8th house is about. During this period, death doesn't look so bad at all.
