Knowledge of Solomon
I like to imagine Billy treats Solomon like fancy google.
Random kid: Captain Marvel! I lost my cat! Have you seen him?
Marvel: Dont worry I'll find him!
Billy, mentally: Cats near me.
Solomon: Billy, thats not how I wor—
Billy, still mentally: Cats in Fawcett city.
Solomon: ..oh what the hell, Fine here.
*Billy gets mentally flashbanged by the location of ever cat on earth*
Captain Marvel: ... *screams*
Random kid: CAPTAIN?!
Billy, low on cash: *looks under soggy newspaper* Where did my quarter go...
Billy: *looks around* SHAZAM!
Solomon: Billy, thank goodness, black ada—
Marvel: shh... Quarters near me
Solomon: Billy this is really important, hes going to—
Marvel: Quarters near me.
Solomon, grumbling: ..it's under your foot
Marvel: Oh, yay!
Batman, going over a mission: Diana, I need you and Captain Marvel to go undercover and collect the vase.
Billy, mentally: Is it vase or vahz?
Solomon: Well, you can use either or, but it infact changes based on dialect, for example, as we are currently in—
Billy, mentally: Disguises—shopping
Solomon: what
Billy, mentally: Disguises, cheep, under twelve dollars, size XL
Solomon: ...
Billy, mentally: ..please?
Solomon: *sigh* go to the shop near the Binder Subway..
Marvel: sounds good to me Batman!
Wonder woman: Yes, that sounds good.
