A/N: It's a day late, I know, I'm sorry, but things came up and I was at a party and stuff so yeah. Anyway, here you guys go.

Gabriel and John arrived at the abandoned garage a few minutes later, John with his gear bag and Gabriel still holding aloft the weapon. 'Cassie?' he called out gently.

'Over here, Gabriel,' replied Castiel upon hearing his brother's call. He walked over to one of the cars to find his brother with his wings wrapped around the two Winchester boys.

'We'd better get going now,' he said to the other angel.

'Wait, you're leaving?' Dean asked as he rose from his resting place to look Cas in the eye, even though the other avoided his gaze.

'I have to, Dean. I'm sorry.'

Gabriel looked between them curiously. Cas wasn't usually one for going against orders. He hoped his baby brother hadn't fallen for Michael's vessel. 'You know what you're gonna have to do, Cas,' he said quietly.

'Do I have to?' Cas asked as he turned to look at Gabriel pleadingly.

'Sorry, bro. They're just the rules, I can't stop it.'

'Do what, Cas?' Dean asked, grabbing hold of his friend's arm. 'What's he talking about?'

'I have to make you forget, Dean. About everything. Abbadon, Gabriel, everything that occurred in the time we have spent together. All your memories of me.' Cas sniffed before continuing. 'They all have to be wiped from your memory.'

'Is what he's saying true?' John asked from behind the archangel. 'Will we all have to have our memories wiped?'

'It's part of the rules, I'm afraid,' Gabriel explained, turning around to look at the hunter. 'None of you can remember this. Not you, not Dean, and not Sam either.'

'And if we try and stop you from doing it?' asked John stubbornly.

Gabriel smiled darkly and spun the blade in his hand. 'You can't stop me if you don't remember me,' he said as he flew so he was stood behind the broad figure. John turned, startled and unready, but Gabriel was faster, and moved his fingers to the hunter's forehead and removed his memories before making him unconscious. 'One down, two to go,' he said, turning to his brother.

'Gabe, please.' The archangel paused; Castiel never called him that unless he was on the verge of pleading.

'Why not?'

'I promised to look after him.'

Gabriel rolled his eyes and turned to look at Sam. 'Hey, you okay?'

Sam nodded tensely from Dean's arms. 'What did you do to our dad?'

'I made him forget, then I sent him to sleep,' Gabriel explained calmly.

'Will you do that to us too?'

'I don't think Cas here is gonna let me,' sighed the angel. 'So here's what you're gonna do – and you listen up too, big boy – you two aren't going to tell your dad about anything. Not angels, not me or Cas or anything that's happened in the last few weeks. Got it?'

Both of the Winchester boys nodded seriously to show they had understood, and Gabriel motioned for Cas to get out of the car. 'I won't make them forget, but you can't stay with them permanently.'

'Wait, Cas still has to go?' Dean asked incredulously.

Castiel extracted himself from the hold he was in, and turned to look at Dean. 'I'll watch over Dean. Pray for me, and I will find you.' He turned to his brother. 'We should take them to another motel.'

'Okay, okay,' Gabriel said as he grabbed hold of John's unconscious body and hoisted him onto his back easily. 'Let's go, and stay with me this time.'

Dean and Sam grabbed a hold of Cas and then a few seconds later were standing in another clean motel. Then, another flap of wings and Cas and Gabriel were gone, without saying goodbye.
