To me it read like Jack was in the area following up on his missing brother when gardie came through selling his "procured" motor bike parts. They linked up, knew each other from back-in-the-day, and decided to find what was left of Jack's brother upstairs. Gardie had a comm call with Code and realized that Mike had mentioned something about the scavv team(you guys) earlier off-camera and that it would be fun-on-a-bun if this became a combined effort to liberate the nazis of their wine cellar and now Senor Greene. Again, that's just how I read it and it's been said in polite circles that I'm a bit dyslexic.
No, that's the basic gist. Gard was contacted to see if he was available for the job, but he was out of signal range until he got to the tower. He saw that there was a scav operation going down in the elevated and assumed, correctly that you guys were that. Confirmation was given and high-fives swept the land.
Yeah, you guys are 20 floors apart by stairs, 7 by open elevator shaft, and there may still be a fire burning for all you know...

Anyway, rolls!
Fear on Machete - 6d6.hits(5) → [5,2,2,4,4,5] = (2) beat
Fear on Digger - 6d6.hits(5) → [5,1,2,1,2,6] = (2) beat
Fear on Ruckus 2.0 - (silly bugs..) 6d6.hits(5) → [5,5,5,3,3,6] = (4) lol robot immunity
Confusion on Devo - 6d6.hits(5) → [5,3,4,5,4,5] = (3) Beat
Holland's Levitate on Devo - 16d6.hits(5) → [1,3,2,4,5,3,4,3,5,4,3,6,4,3,5,5] = (5)
Gonna need a roll here if Devo's against the idea. Levitation is generally resisted with Body + Strength for an unwilling subject. I suppose cover and counterspelling would factor into that as normal.
More details coming.
