It is a difficult decision! Rezo getting stuck would embarrass him (good) and then we have the mental image of the significantly smaller Lioriley trying to pull him out.

otoh I like the idea of an alarmed Rezo hovering nearby Lior and going "Uhhhh okay a fire spell would be a bad idea, wouldn't it"

alternatively for maximum slapstick absurdity one person gets stuck and then when the second person barges in to try and pull them free they both get stuck
