It wasn't a long conversation once the Round Table was called. Obviously, Lady Morgan and Sir Galahad were excused, and Merlin sat in for them, even using a bird as a watcher for them so that they could at least hear what they were discussing.
For the most part, the Round Table agreed that whoever had sent the giant to them probably didn't have good intentions. Giants were normally docile creatures, and rarely attacked. At least, the ones who lived in this area.
It had something to do with an agreement that had been struck with the help of Merlin, so they shouldn't have even considered attacking Camelot. It was a worrying trend, but everyone on the Round Table was going to remain vigilant.
Artie is doing her best, but sometimes, those feelings come sneaking in.
