It's so evident everyone watches RWBY that no longer does anyone mind two spoilers in the picture without the tag. With only 2 episodes left, the season might also end with a cliffhanger... It would be fitting.
Visually, Tewi's pushing close to loli. In-universe, Udonge is the youngest there by..what, centuries? It makes situations like this pretty interesting.
^^ we have lolicon on Flandre and Suwako and they're both well over 100 years old. I'd say from the looks of it Tewi could totally warrant the tag in this pic.
I'm not a big ReiMari fan, but I gotta say that I still prefer them older when they do... stuff... like this. As is the case for most characters, really... but, what can ya do, it seems like this dude likes ecchi lolis (what a waste of his decent drawing skills).
