Will probably trigger as Reflexive Teleport has a Move [2] element. It's a Blue ( Move ) / Orange ( Boost ) card with a Movement Icon.
Yeah, I know. But it shouldn't, since you're teleporting, you can't fly because you're not actually going through the intermediate space. Mechanically, flying doesn't add any benefit not also provided by teleporting. I didn't mention it in the OP because I didn't grab a screenshot so I may be misremembering, but I think for some reason the flight also added a square or 2 to the movement I should have gotten, which is definitely weird.
Right, teleport allows you to do more than fly does since you can also move through blocked spaces. The fly is completely unnecessary.
From a game POV, Flight Aura says "Whenever you play a Move card", so it shouldn't respond to reactions. If this is considered a bug we'll need to also check Teleport Self, Rushing Aura, Energizing Move, Dodge, Hard To Pin Down, and Jump Back.
