Hirogaer, Glorohtar's father and senior advisor to Thranduil, sat at home, waiting for his son. Of a suspicious nature, he followed his son that night to see where he was going, only to see him with that... human. He lay in wait for him. He heard him enter the house.
'Father! What are you doing here?'
'Oh, I just wanted to talk to you. Where were you just now?'
'I.. was just out with some of my friends.'
Hirogaer smiled. 'That's strange. I could have sworn I saw you at the lake with that...' the anger in his voice was barely disguised, 'human scum, Farothwen, or whatever that fool Beleglor named her.'
Glorohtar froze. He never dreamed his father would find out. What would he do to him? What would he do to Farothwen? No... I cannot keep living in fear like this. I must defend her.
'Well, you are right, Father,' Glorohtar replied coolly. 'You did see my wife and I.'
'Your wife? She is your wife? And who bore witness to this "marriage"?'
'Ilúvatar and Manwë,' Glorohtar shot back. 'And you cannot do anything about it. I love her, and you can't stop us being together.'
'Oh, I can't, can I? Well!' Hirogaer grabbed his son by the arm and pulled him so hard that he left marks on his arm, and threw him into his bedroom. He proceeded to lock his door from the outside with multiple locks.
Glorohtar banged on the door and shouted, 'Father! Let me out! I swear I will kill you if you do anything to Farothwen!'
Hirogaer shouted in reply, 'I would like to see you try anything.'
Glorohtar's bangs and shouts ceased after a few hours.
