The situation is not poisonous, there is a protest walking to the ground and that is that.
And the bus welcomes have not happended because Sean Dyche removed the players arriving together via coach. They arrive at the ground in the own car. I'd imagine that last night the club had ordered the first team to arrive by coach so that it gave the fans the chance to do a welcome, which they gracefully responded to, in numbers, yet again.
You are trying to create a narrative that is not there and its quite embarrassing; the atmosphere inside the ground, home or away, has not been changed.
