Head down the stairs. When asked a question by Hugh reply with the top option ('Yes') and he’ll tag along. His party is as follows:
If Snivy was your starter
If Tepig was your starter
If Oshawott was your starter
You now need to explore the sewers. Walking around in this area triggers random battles as if you were walking through grass. What’s more, all battles are double battles as if you were walking through dark grass. The double battles themselves work differently to normal double battles however.
Instead of you using two of your own Pokemon and controlling both, you control one of your own and Hugh controls one of his. Between every battle while Hugh is travelling with you, your Pokemon automatically heal ! Even if fainted, they’re restored to full health. This also goes for Hugh’s Pokemon.
Every time you begin another battle, it’ll be at full health. This is an excellent opportunity to take advantage of, as you can train without the need to run back and forth healing you Pokemon whenever they become too weak. Once Hugh goes back off on his own, the healing between battles no longer occurs.
Note that all trainer battles here excluding the one involving the two Team Plasma Grunts, are single battles and Hugh will take no part in them.
Note : The layout of the sewers differs slightly depending on the season. If playing during Spring or Summer, please continue reading on to the next page: Castelia Sewers (Spring/Summer) . Those playing in Autumn or Winter should skip ahead to the Castelia Sewers (Autumn/Winter) section.
