I am going to have a hard time with this. And, keep in mind that I am looking at the chart through the lens of "what happened to Caylee?"
Sun and Mercury opposing Neptune. Mercury inconjunct Uranus
Reinforces the Neptune issues.

the above also reflects the mystery of her unknown father, and the possible lying about the same. Also unusual sudden events
Mercury and Saturn squaring Mars while Venus and Pluto both sesquiquadrate Mars, Venus squares Pluto. Moon inconjunct Mars
This is a horrible set of aspects.
suffering, separation caused by disputes, arguments, by force.
brutal and coarse expression of feeling, hastiness, premature action.
Now, the above words come straight from Ebertin's Combination of Stellar Inluences.
These aspects are consistent with something awful happening to little Caylee, as well as all the lying and deception about it. I can't be sure, because of Neptune and all the "water" shown by the 4th house and 8th house whether Caylee will ever be found. I am also not sure that we will ever get the total truth about what happened.
I wish I could find a ray of light, or hope. I will have to keep looking.
I could say more about which planet rules what, but am too depressed by it all.
Adding this: With Scorpio on the fourth house, and Pluto, the ruler in the fourth, there is a possibility that Caylee's little body was placed in a dumpster somewhere. The reason I say that is that Mars, Saturn, and Pluto rule garbage and garbage collection. If this is the case, and I do not know that it is... (just my specualtion)... Cayleee's body may never be found, going back to Neptune.
