Requesting the help of a divinely-protected brother Jadelyne's urgent request for Loki and Brian's assistance
sent Loki departing from that group abruptly, probably rudely, and he probably didn't care. He'd figure out how to charm forgiveness for the slight out of the Etherian royal family later.
He stepped out from in-between in the penthouse on the top level of the building. "Calm yourself, JARVIS," he said. Only those given explicit permission were allowed in the penthouse, and usually, only with escort of an official Avenger, even for those who could teleport. "I would not break the rules regarding the sanctity of the penthouse without good reason." He looked out the glass, down the walkway that sometimes doubled as a runway of sorts, whenever the Avengers had to use more old fashioned methods of travel.
At the far end, sitting on the edge and looking out over the city, was Brian.
"I have need of that man out there, and it's urgent."
"My programming dictates that I shall have to tattle on you to Mister Stark," JARVIS replied, the lock on the door out to the walkway clicking open despite that. "Shall I include a notice to him of any impending danger?"
"No need, JARVIS," Loki said, walking to the door. "We simply need Brian's unique talents and connections at the hellmouth. If Tony wants an update, I'm sure Barton and Mooj will appreciate another ear to gibber at."
"So noted, sir," JARVIS said, locking the door behind Loki once he'd stepped outside.
"I hope I don't startle you off your perch, Brian," Loki said, walking towards him. "But Jadelyne requires your services."
