Emmerdale spoilers! Arson attack! Has Brenda’s revenge on Bob and Laurel gone too far?

When a fire is deliberately started, has Brenda's revenge on Bob and Laurel gone too far or is someone else to blame?

Bob is trying to keep things civil with Brenda for the sake of his twins, Cathy and Heath.

The tension is unbearable when he asks her when it’s convenient for him to pick up the rest of his belongings but he’s grateful when she appears to be taking everything calmly.

However as Bob moves his stuff into Laurel’s house he’s worried to suddenly spot smoke rising from near the pirate ship play area.

Has Brenda deliberately started a fire as revenge or could there be another culprit who wants to make Laurel and Bob suffer?
