i think they are neat :)
(no but i have a lot of thoughts actually, i just cant write them all down lol)

so like, we saw from the hollow mind that they were pretty close as children!! i would even like to think that Philip might have been a bit dependent on his brother, so the whole “betrayal” probably hit deep (especially considering he did an murder lol)
he saw Mary as like someone influencing his brother to sin, while Caleb was just in genuine love! Caleb was probably very happy that his brother and his wife would be able to meet and then did Philip commit a murder and Caleb was probably not as happy anymore lol

idk i have a lot of thoughts but i just cant turn those thoughts into words
