Drew

Drew is quite immature for his age-- almost 50 years old-- and most of his life has passed him by on account of focusing on his 'nerdy' interests: reading fantasy and sci-fi books, playing computer games, building kits, watching tv... 

He doesn't consider himself too much. One could call him a 'go with the flow' type.
He allows the mother of his (now preteen) child to walk all over him, and finds it fair since he wasn't the most present partner when they were still together. 

He is a bit careless with his own personal matters, as stated above. He has a lot of enthusiasm but not much energy to give it, much preferring for good things to come his way and for him to partake until they go off on their own.
Overall a gentle soul, not an outrageous bone in his body.
