Anon I love your brain

Cause yes, Vstrid with plant power would hold down and tie up Beef and Siv. But also consider dragon Siv. Beef would gladly be tied up any day, that's a given, but Siv. Siv can breath fire, and maybe he likes to be a bit bratty and burn the plants.

Which is fine. Strid can just gag him with the plants instead. And maybe, you know, just maybe he shoves them down Siv's throat too. Holding Siv's mouth open with some, and moving in and out with others. <3
