There's no need for two hands to take possession of Thot. She is a small bird, and she comes willingly. But Ellis reaches with both hands. One to provide a perch, and one to catch hold of Silas' hand before he can draw back.

His thumb presses gently over the green pulse of the anchor embedded there. (He is thinking of Wysteria, ensconced in her infirmary bed.)

"Thank you."

However businesslike this hand off has been, Ellis is not convinced that this is small thing Silas is offering by giving over Thot into his care.
