Instead of being able to recite the words of the Chant, Bruce lapsed deeper into whatever hallucination was holding him. She took a step back away from him, but he was quicker than her, and his hands closed around her shoulders, holding her tight. Blodwyn immediately reached for the spare hair-pin that she kept in one of the hidden pockets of her skirt - which served the purpose of both holding up her hair if she need of it or being a tool which she could easily stab into her open palm.
But Bruce did nothing but rave and soon enough let go of her shoulders and she did not need to resort to any dire actions which may very well have spoiled the situation even more. This was exactly why the Chantry should have never imposed the use of phylacteries, why they should never have so ignorantly dabbled in blood magic themselves and chose to cover their actions with hypocrisy.
Blodwyn's expression changed from one of anxious concern to approval when Ceallach came back to them with a bottle of lyrium in hand. She could not have been more happy to see his face right then and there. She offered him a smile of sincere gratitude when she slipped her the lyrium, "Yes, this is it exactly. Thank you." And now all that had to be done was to offer the lyrium to the raving Templar.
She quickly uncorked the lyrium potion Ceallach had handed to her and held it out to Bruce, just as he turned to ask her what had happened and informed her once more that he required lyrium. "Nothing happened, Ser Le-Guy, you merely needed some fresh air," she said to him, polite as ever, choosing to not mention that this situation had just unfolded before her eyes and the things she had heard. Blodwyn glanced over at Ceallach, hoping that he would not make mention of it either. "Here, lyrium for you," she told the Templar, gesturing at the bottle that she was holding out for him to take, "it was Ceallach who so quickly procured this for you at my bidding, and it is him you should thank for being so quick."
