Mmm yes Bonnie the biggest battler in the show.
I really don't see how it's forced after over a year of no one taking issue with it then suddenly everything about Bonnie and Puni's relationship was fake and nothing about it was real or genuine , seems like one hell of a reach to me
Also you haven't been watching this show long enough if you honestly try to say battling and bonding are mutually exclusive
The only true Kalos bond from the group would be Serena and her Pokemon, ironically enough. They've messed around in more meaningful ways than the rest of the team, who are all reduced to killjoys excluded from silly conversations.
