Heheh.
Chaos, to me it seemed that no matter what Derek does, he won't be able to reach Erilyn. You will have to go a bit further than bending down at the knees (dohoho). One of our characters will have to suspend themselves to catch her, I think. But you can look at it two ways:
a) Tahan arrives just as the fight begins, observes most of it, then jumps in as Derek wants to help
b) Or Tahan comes later but sees Derek struggling to reach Erilyn, watches him for a bit, then jumps in
Either I feel are completely valid temporal interpretations.
But if you don't want Tahan stealing your thunder (wait if that was the case Leonardo should catch Erilyn in his arms), we can work something out too ;). But doing a coop post might not be bad. You can even hijack the little one in your post so you don't have to tip toe.
