Thinking about all the parents of the Fellowship during the events of the War of the Ring.
Thinking about Saradoc & Esmeralda Brandybuck and Paladin & Eglantine Took, none of whom have any idea where their sons are.
Thinking about the Gaffer, seeing a creepy hooded Man asking for the whereabouts of his son’s boss and then hearing that said son’s boss’ house has been raided and his son is nowhere to be found.
Thinking about Bilbo, knowing that his dear nephew is going into danger because of his own actions so long ago and might never return.
Thinking about Glóin, having to come home to his wife in Erebor and tell her their son is facing life-or-death danger for the first time.
Thinking about Elrond, the wise part of him knowing what must be done vs. the paternal part berating himself for sending his beloved foster son into such peril and wondering if he’ll ever be able to look his daughter in the eye again if her fiancé doesn’t come back.
Thinking about Thranduil, finding out that his only child has entered the war with the very same enemy that destroyed his father and 2/3 of his army.
Thinking about Denethor, trying to protect and defend his entire kingdom while constantly wondering why his favorite son still hasn’t come home.
Thinking about all those parents, having to spend month after month with absolutely no idea if they will ever see their sons again.
