You're probably Bruce Wayne's closest friend and probably the smartest, so of course when Tim was having troubles with some random school work, and you're always hanging around somewhere near anyway, Bruce , at his wits end can't help but just call you, you're the type of person who's so loyal you'd come and help anyone who asks for it if they're close enough and you care about them enough, it's part of what Bruce likes about you, you're one of those people he wouldn't hesitate to drop everything for either

So now Bruce stands, arms crossed over his chest amused as you explain things to Tim and talk him through the work he's doing, he's a smart kid, but damn sometimes with school work it takes him a second

"Apparently Tims teacher barely goes through the course work, he's always stuck copying notes then meant to just remember everything, doesn't sound too fun" Bruce comments gruffly and with a ghost of a smile, only you manage to bring that emotion out of him
