Quick backstory so people understand what's going on here -- Shero's Mother died when he was just 3 years old. He began out shy and nervous, but as he grew up, he got braver and more outward. Every step of the way, he felt his Mother's spirit with him. He never paid attention to her, since she couldn't physically help him with his real problems (Mental health, bullying, and so on) Finally, he gets older, and acknowledges his mother's presence, before soon he's able to meet her in the afterlife, aka the last scene "Thanks for always being there"~
