Jake just arrived after completing his mission at Redwood city, he saw that there was a commotion going on near the restaurant where his mother worked and decided to check what was going on over there.
Jake saw that her mother was bleeding profusely as some people from the restaurant were helping her.
Watching this scene Jake was able to control his feelings as he saw her mother bleeding and thought, 'Surprisingly I was able to control my feelings when I saw mom Bleeding, back in the past I would have surely been enraged and acted rashly. It seems that my Training had a lot of effects on my body but it was the mental state that changed me the most. I wouldn't have realized about this unless I encountered such an incident.'
Jake calmly approached her mother as he saw her bleeding as he wanted to know about the situation, as soon as he saw Evan Laguna he understood what was going on over here. He remembered the past events as he saw Evan.
