Oh, I remember this. Definitely one of my favourite arcs ever! I never check who the writer is before I read a comic, so after a couple of pages, I was like "Dick and Tim being adorkable Bat fanboys, exploring father-son relationships, Dick being batshit crazy and the Bats talking out their feelings?? MUST be Devin Grayson!"
Apart from a couple of blips during her run on Nightwing (Tarantula raping Dick and multi-millionaire heir to WE sleeping on newspapers because he be so emo, bwahahaha!) I really love Devin's work. I think she's a writer like Tomasi, who channels what most fangirls mature readers want - Bat noogies emotional depth and character exposition.
She's like DC's Sera Gamble, only without the gratuitous sex. XD
Oh, and I love, love, love Dick throwing himself off a building to see whether the fall was survivable. That boy has a limited conception of his own mortality, really. No wonder he drives Babs crazy! *snuggles him*
