I've beated the 7th gym leader on Hoenn region, so I want to go to route 127 but two sharpedos blocks me.
After this I go to route 126 on underwater to go ahead with story but Roxanne blocks me. I read to send Roxanne away from the underwater I've to go on route 127 to fight with aqua team AND THIS IS A BIG PROBLEM because route 127 is blocked by Sharpedo... what can I do now?
