Marcus was a little taken aback by the vehemence of Bryony's words, mostly because she was almost never sharp with him.
"When have I ever lied to you," he responded quietly after a moment, more of a statement than a question. There were plenty of things he had never told her, but that had been in order to protect her from any possible repercussions, but he didn't consider those to have been lying, per se.
Sensing her desire to move away from the topic, Marcus nodded slightly as he agreed, "I'm sure it will be wonderful."
