So the knobby thing was the first leaf, albeight deformed........
Wish someone would jump in with some guesses, I've not had any experience with virus infected plants (thank heavens). I don't know if a new growth (keiki) could be virus infected and not the mother plant. The main plant looks good, the leaves have good color and shape.
I just don't know. You have a "wonder".
Keep it going and see what the next bloom sequence looks like.
By the way, I LIKE the blossom, the lip is a bit deformed too but it kinda looks like a Catt/Phal cross. LOL
