[Nikitus]

Hello.

Are the following sentences grammatically correct?

"Kelly walked in the subway car. She looked at Kevin, and stopped a few feet from him. Kevin was standing alone, far from other people, and strongly grabbing the handles of the subway car, looking sideways and backwards repeatedly. Kelly approached to Kevin."

Thanks.

 

[teechar]

Kelly walked [STRIKE]in[/STRIKE] through the subway car.

or

Kelly [STRIKE]walked in[/STRIKE] got on the subway (car).

Those don't mean the same thing.
