Poor Ned doesn't want to hit Wilfreda to begin with, never mind get in trouble for doing it, so good choice on his part. If it happens to help Wilfreda sell her lemonade then that works, though I happen to agree with Victor still since this test was based on an erroneous premise. (But in his shoes I'd say I was just thirsty and drink the lemonade anyway because what's the worst that could happen? ) Also, it's so cute that Victor had to cover his eyes because he was worried about her.
Wilfred is bullying the bully, and the romantic in me sees them married in the future.
As Wilfreda does her Scrappy-Do impersonation.
