Alex just listened quietly. Somewhat amused when Amber was insulted... 
[i]... They? Who is they?[/i]
When the medium-sized creatures came in. Alex has never seen them before. A small very bearable amount of heat was emitted by them.
Alex would much rather fight then run. His pride and honor wouldnt let him. A few moments later he had hear the woman's name. Elsa. 
He still had not introduced himself. Mainly because he did not like many things crated by humans including names. Animals live their whole entire lives without such labels.
Sharp objects or water? Alex could provide both if he wasn't in such a weak state. Not having eaten much. Living purely off of his own emotions majority of the time and a few berries. He already had sharp objects with him though. No need to create anything, doing so absorbs much of his energy. 
The retractable hooks on his gloves became came out again. 

[i]Counting on attracting them?[/i]

"... We wont need the river." Alex says, Somewhat arrogantly. He waited in his fighting position when a few more of the creatures had entered his field of sight. "...More of them." Alex said this very dully while counting approximately 3 of the fire-loving creatures.
