When Rainbow Dash got Lightning Dust kicked out of the Wonderbolts Academy, she never thought of what Lightning might do afterwards.

Rainbow Dash had crushed the dreams of somepony who couldn't care less about others getting hurt and shrugged off nearly killing five ponies. Didn't she ever think that there may be consequences?
