Blaine wrecks his car and has to call a mechanic (Kurt) while on the phone with kurt he stands up on a large rock in the playground to find the shop. Later on Kurt makes Blaine make the screeching sound the car is making.
I'm not sure but I think later Blaine repeatedly comes back again with car troubles that he does purposley and constantly asks Kurt to fix them and burt notices and tells baline to just ask kurt out.
I'm pretty sure it ends with blaine putting a ring in the exhaust and asking Kurt to take a look at it
*mods i hope my tags are right, if not let me know and I'll fix them*
