On the surface of Mars the Uber Ethereal was surrounded by screens showing what was happening on Earth. They showed Vicky and Fred blowing up the downed Supply Ship in Torbay, the Visitor ships being blown out of the sky and the Zoombian ship that materialised above a school before vanishing after unloading a group of soldiers to attack some random house.
He knew the Vintos were on Earth anyway, but anybody who can take down three ships in three days were trouble; anybody who can go head to head with the Zoombians with such strength and bravery were going to be trouble; anybody that could takedown his best Sectoid soldiers with only two people were going to be trouble - he'd received a message from one of the Sectoids that informed him that the girl was somehow immune to their psionic grasp in a way that suggested that she was already under another psionic influence.
The Ethereal knew that these seemingly Super-Powered children were going to hinder his invasion more than XCOM did the first time-round.
Without the Snakemen he knew controlling the Crysillid would be near impossible - but the only solution with forcing them out and executing them because they were native to Mars and as a result they weren't spread throughout the entire galaxy fighting the reptiles and cats.
He decided after five days of thinking to move the invasion up from May/June to the end of February. Meanwhile he decided to send some of his soldiers to attack the house of the new Super-Powered threat.
