@@LyviaXO_ To be exact Lux is Garen's little sister. This cinematic used to have a big impact because Garen back in the day didn't know Lux has magic. And also magic is forbidden in Demacia, where they are both from. This the first cinematic in which Lux is using magic openly in public. Meaning Garen now knows and approves. He suspected that before and was trying extremely hard to ignore the evidence right in front of him in order not to be forced to put his own sister in prison. So this cinematic is pretty much an end of an era for both Lux and Garen. They are together now. No more secrets. Also Lux summons Gallio, which may be why her magic is allowed. Gallio is way too much of an asset for Demacia to lay a hand on a mage who is able to summon him at will.
