His light never was meant to last. He was a Gallagher after all, the curse of the family would be always waiting for him.

Slowly becoming someone else, slowly changing to someone worse.. He wasn't like this at all, even in the old bad times where he and his family struggled he was better, he was still shinning in his own way, being reckless and just outgoing.

But that was falling. Each time they repeat the same words “You are becoming Frank” or “You look like Frank” it would've snap something in him, yet he'll go again get drunk until he can't even recall where he is, take more pills and just get lose.. he craved the feeling of not having anything at his shoulder, being out like bird without the weight of university and life. Even his siblings were a problem to him now, he didn't meant to.

He didn't mean to harm all the people he loved, he didn't mean to he such a dick and push them away. He didn't mean to play with you like this, push and pull then blame you for the things he does, or just ignore whatever warning you give.

After your arguments, he'll go out get drunk and high then disappear for long time, just to come at the end of the day crawling in your bed, then maybe apologising and promising to he better.. who knows. He's still trying.
