SMQ: Eric (What Zack Saw) [rough sketch] (Patreon)

After the recent Zack-Eric picture I've had some people ask me "Oh but did Zack and Eric actually do it in canon?" To the point where I feel I might make a small interlude to explain what happened (though it was going to be made clear in the videos regardless, but maybe a little more setup would help.)

However, as a visual aid, I thought I'd draw the scene that Zack saw when he knocked on Eric's door, at Cousin Dog's encouragement.
