"What the heck is the meaning of this?"
Elijah has just come back trip, and the first thing his grandson shows him is a video of his sister confessing the truth about her death. His old heart can't handle such a revelation.
His heart says that he should believe it, but his stubborn mind is saying that he should not believe it because this is might be one of Kyle's schemes.
In the end, Elijah's stubborn mind won. He chose not to believe it; he doesn't want to believe this video that has his sister's face on it. For all these years, the man that he blamed for his sister's death is Marcus' brother. That has been in his mind for a long time and has been engraved.
"Grandfather, the meaning is already in the video you just saw. There is no need for me to explain it to you." Kyle said in a straight face.
