Kagome makes things worse with sit commands. Inuyasha completely wrecks the slightly broken bike and is later forced to crash into antiques he was helping grandpa move.
The Adamant Barrage doesn't work in the Modern Era.
Kagome's friends meet Inuyasha, finding him to be (obviously) odd but a nice guy; feeling happy for Kagome having a good boyfriend. Their next job would be getting Hojo to back off.
Despite the fact Kagome mentions her boyfriend's ex being back in the picture again, the girls don't bring it up when they talk to Inuyasha. Likely they wanted to get a grasp on his character; having gleamed from Kagome that he is devoted to who he loves, but has trouble letting go of the past.
