ok for those wondering when ash contacted liza and how charizard just showed up. Well they never really showed ash contacting liza but i mean common ash is not psychic. When noland asked ash what pokemon will you use ash? Ash said ill use that And looked at the sky. everyone else was shocked to see charizard except for ash meaning he contacted liza sometime in the day and he arrived during the night time its not that hard to believe. I dont think liza will be there brock called liza during the johto league to send charizard for ash but liza didnt show up so the same thing is being done here.
