I never noticed this until it was brought up here, but I'd guess that Gypsy got the drop on them, because they never dealt with her before. She has the benefit of surprise. Just like Vibe was able to use the benefit of surprise on her. If so much stuff is covered by Speed Force (see LEGENDS), then why can't a lot be written off as Vibe Force or Multiverse Force?
Do you think that Cisco and Gypsy are multiverse counterparts? In other words, Cisco was coming on to his female doppelganger. And by the way, that was hilarious how he kept trying to make time with her even while she was trying to kill him.
I also thought it was funny that always so correct Julian had to say "Multiple universes" not "Multiverse."
