enjolras and grantaire didn’t just hold hands and then die, grantaire probably gripped it tighter and enjolras squeezed back as he was hit with the first bullets and maybe grantaire felt enjolras’ muscles go slack before enj died and let me tell you, not just seeing or hearing the person you love die but feeling it must have been horrific
Now, I know the blind man is supposed to be Grantaire and the Light is Enjolras, Hugo has weaved enough light/darkness symbolism into his hell hole of a novel for that to be clear
but consider
Enjolras keeps dismissing Grantaire. All the time. He never realises the extent of Grantaire’s feelings and faith for him. Not until the very dusk of his life, when darkness is closing in around him, when Grantaire manages to make him smile.
Then, truly, no one loves the light like the blind man
