Hello? Yes I've been watching a lot of Elena's videos and also know about JC. I do believe Elena's contacts are legit and what she is saying is true; but she never claimed that Mars was fully liberated, only that there are ongoing operations there with the goal of liberation, including empowering the local insectoid & reptoid species to fight against the Draco & other negative factions.
As for JC, I think she picks up on some truthful information including dark happenings underground; she also picked up on the Moon being liberated by positive forces, and certain manipulative technology being taken over. But she is not a scientific remote viewer, just claims to go on psychic journeys, so it's hard to say if some of the stuff she says is truth or bias/imagination. Watch with skepticism. Regardless, she is entertaining, and I think they both have good intentions. Megan Rose is another psychic with galactic contacts who speaks about some far out stuff.
