Lade fled… that is, went to the roof to have his conversation. It was one of his favorite hangout spots in the Zone, not to mention it was safer than his apartment here, at least as far as the risk of being listened to was concerned. In the apartment, with all the furniture and so on, there were many places where someone (for example Blanc. Most likely Blanc, or someone working on his orders, as it was unlikely anyone else would dare) might hide listening devices. It would take a while for Lane to clear the place.
As for the roof? It was just a plain slab of concrete. With no place to hide even a tiny listening device. Not that no one had tried - the place was bugged - but Lane just crushed them into dust under his military boots. Then, he sent small blobs of Toxic Ooze to destroy the spy cams on the nearby buildings, activated Mana Scan to check the area one last time, and only then did he finally pull out his phone, and call Ava.
