Snap! Not only are we going to get to see Cisco getting more comfortable with his Vibe talents, but we're going to get a brand new (to the show) hero to help him along with his trans-dimensional powers. Both Gypsy and Vibe have precognitive abilities, and are able to project their consciousnesses outside their bodies, so perhaps she'll have a new trick in this respect. Both are also known in the comics for their agility and flexibility, so maybe Gypsy will show Vibe some battle-ready moves, and we'll get to see him use his wave-based powers more aggressively.
