[@JunkMail][@OfWindAndRain]  Yo, as Alex and Dex are touching, what clouds are visible in the sky start to converge and the wind and rain start whipping up even worse.  By their contact, she's borrowing his power and so the passive effect is doubled.  

Dexter is gonna get shocked when Zoey joins the hug, because she has her own charge, and it gets added to the one that Alex will start to generate from borrowing her power as well.
