Before I say anything, just to echo the sentiment that Richmond, this is about you & we are all thinking about you - if there is any way we can help, just reach out to us.
As for the terrible news, I still can't process it- it's a feeble trope that the good die young, but I can't think of a better example - as others have said, he was the best of us a true diamond.
My Comics fandom flame was kept ignited by Paul Von Scott and Bolt when I met them back at those early Dreddcons - Dave's enthusiasm was infectious and his love for the comics I loved just magnified that love immeasurably.
I'm a pretty socially awkward/anti-social type and knowing that Bolt was at a Con made them unmissable, because I always knew I'd walk out of there feeling excited about comics and generally feeding off his energy. Meeting his wonderful kids was always a pleasure too - I'd occasionally walk past the shop in Brum where Dan works and either give him a wave if I saw him in the window or even if I didnt see him there, it would just give me a tiny buzz that I knew that kid and his dad and how golden they were. I have the cuddly Gronk that Izzy made sitting in my geek room pride of place. Dave was not just a great comics fan and creator, not just a great person, but an amazing father. My thoughts go out to his family, because losing anyone is a terrible thing, but losing someone as wonderful as Dave so young, I can't imagine.
Dave had messaged me a week back to chase up a story I'd struggled to get started on the art for (Lockdown creating extra work for me and a bout of what I think might have been a fairly mild but fatiguing Long Covid left me struggling to get my mnd back into drawing mode). As soon as he asked if I was up to try again, I just knew I had to, for him and for myself, because you didn't want to let Dave down, but you knew that the right thing to do was always "Be more Bolt" - as I said, the enthusiasm was infectious. I'd got myself a plan to timetable it out and was waiting for his "green for go" email....
Because I'm a pretty socially awkward/anti-social type I always felt guilty about not hanging around for after-con drinks and that guilt was almost entirely due to that meaning I didn't really get to know Dave, who I always idly wished I'd made more time to get to know, living in the same town Knowing that isn't gong to happen, that I'm not going to see his friendly face at the next con.... Richmond, I can only guess from how I feel about him knowing him only casually, how you feel knowing him so well - please take care and as I say, we are here for you.
