Batgirl (*Spoilers for those who don't know batman movies*)

Okay, so last night my boyfriend and I watched Batman....Forever? The one with Mr.Freeze and Poison Ivy, well whatever. So, toward the end Robin and Batgirl are trying to recalibrate a laser and the positioning of four satellites, she looks at batman and says "It'll take about 1 minute to re-position the satellites." And HOW would she know this? Is she a rocket scientist? Maybe she's been brushing up on astro-physics? Or is there a little sticker on it that says "satellites will take approximately 1 minute to re-position"? She didn't even graduate college! She dropped out!! And she also knows how to street ride motorcycles, though not hard. Little thief goes, steals Dick's (Robin) nicest bike, and loses it off the edge of a damned ruined bridge. NOT HERS!! As you can tell, she aggravates me. Little bitch. Thank you.
