Giles misses grabbing hold of her sleeve by the skin of his teeth. He looks wildly around through the crowd for any further sign of her, unwilling to let it go at just that.

When he thinks he catches a glimpse of her a few feet away, Giles starts towards her...and then he stops, remembering himself. Remembering everything, and why Ginia might not want to be near him.

Shamefaced, this time he just looks after her, silently searching her face for any hint of what might come next, or what she might want or need him to do.
