I think Abigail will cause major problems for John Proctor later on in the play based on the evidence in Act 1. She still has feelings for him from the affair so I think she will get in the way of his marriage with Elizabeth, his wife. We can tell she is already giving off a jealous vibe.

I think John Procter will get caught with his affair in the town, he doesn't want his image to be destroyed but I believe the town will find out one way or another. If word gets out there will probably be problems.
