I dont know (chapter 4)

BROOKLYNS POV:
After school I walked home with Ali.
"Hey Brooklyn at 4th period I went to the restroom and saw you with matt"ali said.
"Yea it was nothing tho" I said looking down holding my hands together.
"Cmon brook what was going on?" Ali smirked😏.
i sighed "okay fine he asked me if i had any plans tomorrow night.which i dont exactly no.what about sierra.what if she beats me up?what if she bullys me? Ali i dont no what to do" i say looking at her worried 😰.
"brooklyn dont let her get to you,shes nothing.and remember im always here for you"ali says.
then we hear something behind us.it sounded like somebody stepped on a tree branch. "Ali what was that"i said."oh its nothing dont worry." ali says trying not to freak me out.
we both turn around and see.....
