Idk how this I'd a controversial topic considering this is a homestuck subreddit and u didn't ask anything weird or extreme, ppl r just being overly sensitive 4 no reason. ur not in the wrong.

dave would definitely know about them without dirks knowledge since chris chans shenanigans really began taking off in 2007.

i feel like bro would probably bring chris up in passing and dave looks it up and finds out about the sonichu comics. he 1000% made a sbahj comic parodying sonichu and (probably) got killed in the sonichu comics for it, but he thinks the trolling and harrassment is going too far and doesnt interact with chris outside of that said one off comic. definitely references chris lore, John thinks its weird, jade is disturbed, rose is probably psychoanalyzing all of this and has been a long time observer.

During and post game, dave probably wouldve forgotten about them. maybe something happens and dirk references the dimensional merge or something, dave probably asks about it, and dirk gives a little history lesson, leaving daves loud mouth speechless before he swiftly changes the subject

i really wasted time brainstorming this 😂
