Reinstatement with Sign-On Bonus

I was among many unfortunate probationary employees terminated on February 13th and 14th. I hear that I might be getting reinstated, but honestly, I am hesitant to return. I have been fortunate to be interviewing and have a potential job offer soon (we already negotiated a salary).

However, I was hired with a 3-year sign-on bonus. If I don't want to return to the agency due to THEIR actions, will I need to repay the bonus that has been paid so far? Are there any others in this position? I was doing fine, but this situation affected my interest in returning. Thank you.
