That would get anyone's attention...
I don't know why, but this seems like more like a scene with a single father dropping the bombshell that he's starting to date again, rather than the fact someone (let alone another super) know his alias. Still, that's why it's *funny*. I can't wait to see what will Simon's undoubtedly (and rather loud, and possibly obscene) vocal reaction to this news.
Between the dark house of Julius' and the general night time atmosphere that has been pervading this comic, it is refreshing to see the bright casa de everywhere. White is definitely a theme with these two. I wonder what their popularity is with the general populace, everywhere kid seems to have a share of fans, but that may be because of his young age and excitable tendencies. White is the symbol of hope, and generally purity. Never mind food bills, their electric bills must be skyrocketing to keep such white atmosphere. However, like I said, I much prefer they brighter panels, to really show off your skill of artistry.
Also I agree with Subaru's caplocked comment above.
